-
-
-OVERVIEW
-========
-
-This package contains C software to implement JPEG image compression and
-decompression. JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images. JPEG is intended for compressing
-"real-world" scenes; line drawings, cartoons and other non-realistic images
-are not its strong suit. JPEG is lossy, meaning that the output image is not
-exactly identical to the input image. Hence you must not use JPEG if you
-have to have identical output bits. However, on typical photographic images,
-very good compression levels can be obtained with no visible change, and
-remarkably high compression levels are possible if you can tolerate a
-low-quality image. For more details, see the references, or just experiment
-with various compression settings.
-
-This software implements JPEG baseline, extended-sequential, and progressive
-compression processes. Provision is made for supporting all variants of these
-processes, although some uncommon parameter settings aren't implemented yet.
-For legal reasons, we are not distributing code for the arithmetic-coding
-variants of JPEG; see LEGAL ISSUES. We have made no provision for supporting
-the hierarchical or lossless processes defined in the standard.
-
-We provide a set of library routines for reading and writing JPEG image files,
-plus two sample applications "cjpeg" and "djpeg", which use the library to
-perform conversion between JPEG and some other popular image file formats.
-The library is intended to be reused in other applications.
-
-In order to support file conversion and viewing software, we have included
-considerable functionality beyond the bare JPEG coding/decoding capability;
-for example, the color quantization modules are not strictly part of JPEG
-decoding, but they are essential for output to colormapped file formats or
-colormapped displays. These extra functions can be compiled out of the
-library if not required for a particular application. We have also included
-"jpegtran", a utility for lossless transcoding between different JPEG
-processes, and "rdjpgcom" and "wrjpgcom", two simple applications for
-inserting and extracting textual comments in JFIF files.
-
-The emphasis in designing this software has been on achieving portability and
-flexibility, while also making it fast enough to be useful. In particular,
-the software is not intended to be read as a tutorial on JPEG. (See the
-REFERENCES section for introductory material.) Rather, it is intended to
-be reliable, portable, industrial-strength code. We do not claim to have
-achieved that goal in every aspect of the software, but we strive for it.
-
-We welcome the use of this software as a component of commercial products.
-No royalty is required, but we do ask for an acknowledgement in product
-documentation, as described under LEGAL ISSUES.
-

-
-1. We don't promise that this software works. (But if you find any bugs,
- please let us know!)
-2. You can use this software for whatever you want. You don't have to pay us.
-3. You may not pretend that you wrote this software. If you use it in a
- program, you must acknowledge somewhere in your documentation that
- you've used the IJG code.
-
-In legalese:
-
-The authors make NO WARRANTY or representation, either express or implied,
-with respect to this software, its quality, accuracy, merchantability, or
-fitness for a particular purpose. This software is provided "AS IS", and you,

-
-ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
-sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
-ansi2knr.c is NOT covered by the above copyright and conditions, but instead
-by the usual distribution terms of the Free Software Foundation; principally,
-that you must include source code if you redistribute it. (See the file
-ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part
-of any program generated from the IJG code, this does not limit you more than
-the foregoing paragraphs do.
-
-The Unix configuration script "configure" was produced with GNU Autoconf.
-It is copyright by the Free Software Foundation but is freely distributable.
-The same holds for its supporting scripts (config.guess, config.sub,
-ltconfig, ltmain.sh). Another support script, install-sh, is copyright
-by M.I.T. but is also freely distributable.
-
-It appears that the arithmetic coding option of the JPEG spec is covered by
-patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot
-legally be used without obtaining one or more licenses. For this reason,
-support for arithmetic coding has been removed from the free JPEG software.
-(Since arithmetic coding provides only a marginal gain over the unpatented
-Huffman mode, it is unlikely that very many implementations will support it.)
-So far as we are aware, there are no patent restrictions on the remaining
-code.
-
-The IJG distribution formerly included code to read and write GIF files.
-To avoid entanglement with the Unisys LZW patent, GIF reading support has
-been removed altogether, and the GIF writer has been simplified to produce
-"uncompressed GIFs". This technique does not use the LZW algorithm; the
-resulting GIF files are larger than usual, but are readable by all standard
-GIF decoders.
-
-We are required to state that
- "The Graphics Interchange Format(c) is the Copyright property of
- CompuServe Incorporated. GIF(sm) is a Service Mark property of
- CompuServe Incorporated."
-
-
-REFERENCES
-==========
-
-We highly recommend reading one or more of these references before trying to
-understand the innards of the JPEG software.
-
-The best short technical introduction to the JPEG compression algorithm is
- Wallace, Gregory K. "The JPEG Still Picture Compression Standard",
- Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
-(Adjacent articles in that issue discuss MPEG motion picture compression,
-applications of JPEG, and related topics.) If you don't have the CACM issue
-handy, a PostScript file containing a revised version of Wallace's article is
-available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz. The file (actually
-a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
-omits the sample images that appeared in CACM, but it includes corrections
-and some added material. Note: the Wallace article is copyright ACM and IEEE,
-and it may not be used for commercial purposes.
-
-A somewhat less technical, more leisurely introduction to JPEG can be found in
-"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
-M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1. This book provides
-good explanations and example C code for a multitude of compression methods
-including JPEG. It is an excellent source if you are comfortable reading C
-code but don't know much about data compression in general. The book's JPEG
-sample code is far from industrial-strength, but when you are ready to look
-at a full implementation, you've got one here...
-
-The best full description of JPEG is the textbook "JPEG Still Image Data
-Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published
-by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1. Price US$59.95, 638 pp.
-The book includes the complete text of the ISO JPEG standards (DIS 10918-1
-and draft DIS 10918-2). This is by far the most complete exposition of JPEG
-in existence, and we highly recommend it.
-
-The JPEG standard itself is not available electronically; you must order a
-paper copy through ISO or ITU. (Unless you feel a need to own a certified
-official copy, we recommend buying the Pennebaker and Mitchell book instead;
-it's much cheaper and includes a great deal of useful explanatory material.)
-In the USA, copies of the standard may be ordered from ANSI Sales at (212)
-642-4900, or from Global Engineering Documents at (800) 854-7179. (ANSI
-doesn't take credit card orders, but Global does.) It's not cheap: as of
-1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
-shipping/handling. The standard is divided into two parts, Part 1 being the
-actual specification, while Part 2 covers compliance testing methods. Part 1
-is titled "Digital Compression and Coding of Continuous-tone Still Images,
-Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
-10918-1, ITU-T T.81. Part 2 is titled "Digital Compression and Coding of
-Continuous-tone Still Images, Part 2: Compliance testing" and has document
-numbers ISO/IEC IS 10918-2, ITU-T T.83.
-
-Some extensions to the original JPEG standard are defined in JPEG Part 3,
-a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84. IJG
-currently does not support any Part 3 extensions.
-
-The JPEG standard does not specify all details of an interchangeable file
-format. For the omitted details we follow the "JFIF" conventions, revision
-1.02. A copy of the JFIF spec is available from:
- Literature Department
- C-Cube Microsystems, Inc.
- 1778 McCarthy Blvd.
- Milpitas, CA 95035
- phone (408) 944-6300, fax (408) 944-6314
-A PostScript version of this document is available by FTP at
-ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz. There is also a plain text
-version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
-the figures.
-
-The TIFF 6.0 file format specification can be obtained by FTP from
-ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz. The JPEG incorporation scheme
-found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
-IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).
-Instead, we recommend the JPEG design proposed by TIFF Technical Note #2
-(Compression tag 7). Copies of this Note can be obtained from ftp.sgi.com or
-from ftp://ftp.uu.net/graphics/jpeg/. It is expected that the next revision
-of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
-Although IJG's own code does not support TIFF/JPEG, the free libtiff library
-uses our library to implement TIFF/JPEG per the Note. libtiff is available
-from ftp://ftp.sgi.com/graphics/tiff/.

-ARCHIVE LOCATIONS
-=================
-
-The "official" archive site for this software is ftp.uu.net (Internet
-address 192.48.96.9). The most recent released version can always be found
-there in directory graphics/jpeg. This particular version will be archived
-as ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz. If you don't have
-direct Internet access, UUNET's archives are also available via UUCP; contact
-help@uunet.uu.net for information on retrieving files that way.
-
-Numerous Internet sites maintain copies of the UUNET files. However, only
-ftp.uu.net is guaranteed to have the latest official version.
-
-You can also obtain this software in DOS-compatible "zip" archive format from
-the SimTel archives (ftp://ftp.simtel.net/pub/simtelnet/msdos/graphics/), or
-on CompuServe in the Graphics Support forum (GO CIS:GRAPHSUP), library 12
-"JPEG Tools". Again, these versions may sometimes lag behind the ftp.uu.net
-release.
-
-The JPEG FAQ (Frequently Asked Questions) article is a useful source of
-general information about JPEG. It is updated constantly and therefore is
-not included in this distribution. The FAQ is posted every two weeks to
-Usenet newsgroups comp.graphics.misc, news.answers, and other groups.
-It is available on the World Wide Web at http://www.faqs.org/faqs/jpeg-faq/
-and other news.answers archive sites, including the official news.answers
-archive at rtfm.mit.edu: ftp://rtfm.mit.edu/pub/usenet/news.answers/jpeg-faq/.

-RELATED SOFTWARE
-================
-
-Numerous viewing and image manipulation programs now support JPEG. (Quite a
-few of them use this library to do so.) The JPEG FAQ described above lists
-some of the more popular free and shareware viewers, and tells where to
-obtain them on Internet.
-
-If you are on a Unix machine, we highly recommend Jef Poskanzer's free
-PBMPLUS software, which provides many useful operations on PPM-format image
-files. In particular, it can convert PPM images to and from a wide range of
-other formats, thus making cjpeg/djpeg considerably more useful. The latest
-version is distributed by the NetPBM group, and is available from numerous
-sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
-Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
-you are likely to have difficulty making it work on any non-Unix machine.
-
-A different free JPEG implementation, written by the PVRG group at Stanford,
-is available from ftp://havefun.stanford.edu/pub/jpeg/. This program
-is designed for research and experimentation rather than production use;
-it is slower, harder to use, and less portable than the IJG code, but it
-is easier to read and modify. Also, the PVRG code supports lossless JPEG,
-which we do not. (On the other hand, it doesn't do progressive JPEG.)
-
-
-FILE FORMAT WARS
-================
-
-Some JPEG programs produce files that are not compatible with our library.
-The root of the problem is that the ISO JPEG committee failed to specify a
-concrete file format. Some vendors "filled in the blanks" on their own,
-creating proprietary formats that no one else could read. (For example, none
-of the early commercial JPEG implementations for the Macintosh were able to
-exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES). This format
-has been agreed to by a number of major commercial JPEG vendors, and it has
-become the de facto standard. JFIF is a minimal or "low end" representation.
-We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
-Technical Note #2) for "high end" applications that need to record a lot of
-additional data about an image. TIFF/JPEG is fairly new and not yet widely
-supported, unfortunately.
-
-The upcoming JPEG Part 3 standard defines a file format called SPIFF.
-SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
-be able to read the most common variant of SPIFF. SPIFF has some technical
-advantages over JFIF, but its major claim to fame is simply that it is an
-official standard rather than an informal one. At this point it is unclear
-whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
-standard. IJG intends to support SPIFF once the standard is frozen, but we
-have not decided whether it should become our default output format or not.
-(In any case, our decoder will remain capable of reading JFIF indefinitely.)
-
-Various proprietary file formats incorporating JPEG compression also exist.
-We have little or no sympathy for the existence of these formats. Indeed,
-one of the original reasons for developing this free software was to help
-force convergence on common, open format standards for JPEG files. Don't
-use a proprietary file format!
-
-
-TO DO
-=====
-
-The major thrust for v7 will probably be improvement of visual quality.
-The current method for scaling the quantization tables is known not to be
-very good at low Q values. We also intend to investigate block boundary
-smoothing, "poor man's variable quantization", and other means of improving
-quality-vs-file-size performance without sacrificing compatibility.
-
-In future versions, we are considering supporting some of the upcoming JPEG
-Part 3 extensions --- principally, variable quantization and the SPIFF file
-format.
-
-As always, speeding things up is of great interest.
-
-Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net.

-=================================================================

-Consumers are increasingly browsing Web based photo galleries incorporating
-high-resolution JPEG images with their mobile devices. These images are
-decoded by the mobile device, and typically also scaled down to fit the user's
-zoom selection on the device's browser.
-
-In order to improve both decode and download times, Qualcomm Innovation Center
-has optimized the JPEG library found on many common OS platforms such as Web
-OS, Android, and Chrome OS. Our team re-implemented several routines to utilize the
-DSP-like SIMD capabilities of the ARM NEON instruction set. These were then
-tuned and tested on Qualcomm's Snapdragon platform which implements the VeNum
-implementation of these same instructions.
-
-The specific areas of focus cover VeNum/NEON acceleration of Inverse Discrete
-Cosine Transform (iDCT) for 8x8, 4x4, 2x2, and 1x1 block sizes and YUV to RGB
-color space conversion. This resulted in a range of 18-32% improvement in JPEG
-decode and downscale times for images greater than 2Mpixels.

-.TH ANSI2KNR 1 "19 Jan 1996"
-.SH NAME
-ansi2knr \- convert ANSI C to Kernighan & Ritchie C
-.SH SYNOPSIS
-.I ansi2knr
-[--varargs] input_file [output_file]
-.SH DESCRIPTION
-If no output_file is supplied, output goes to stdout.
-.br
-There are no error messages.
-.sp
-.I ansi2knr
-recognizes function definitions by seeing a non-keyword identifier at the left
-margin, followed by a left parenthesis, with a right parenthesis as the last
-character on the line, and with a left brace as the first token on the
-following line (ignoring possible intervening comments). It will recognize a
-multi-line header provided that no intervening line ends with a left or right
-brace or a semicolon. These algorithms ignore whitespace and comments, except
-that the function name must be the first thing on the line.
-.sp
-The following constructs will confuse it:
-.br
- - Any other construct that starts at the left margin and follows the
-above syntax (such as a macro or function call).
-.br
- - Some macros that tinker with the syntax of the function header.
-.sp
-The --varargs switch is obsolete, and is recognized only for
-backwards compatibility. The present version of
-.I ansi2knr
-will always attempt to convert a ... argument to va_alist and va_dcl.
-.SH AUTHOR
-L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
-continues to maintain the current version; most of the code in the current
-version is his work. ansi2knr also includes contributions by Francois
-Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

- GHOSTSCRIPT GENERAL PUBLIC LICENSE
- (Clarified 11 Feb 1988)
-
- Copyright (C) 1988 Richard M. Stallman
- Everyone is permitted to copy and distribute verbatim copies of this
- license, but changing it is not allowed. You can also use this wording
- to make the terms for other programs.
-
- The license agreements of most software companies keep you at the
-mercy of those companies. By contrast, our general public license is
-intended to give everyone the right to share Ghostscript. To make sure
-that you get the rights we want you to have, we need to make
-restrictions that forbid anyone to deny you these rights or to ask you
-to surrender the rights. Hence this license agreement.
-
- Specifically, we want to make sure that you have the right to give
-away copies of Ghostscript, that you receive source code or else can get
-it if you want it, that you can change Ghostscript or use pieces of it
-in new free programs, and that you know you can do these things.
-
- To make sure that everyone has such rights, we have to forbid you to
-deprive anyone else of these rights. For example, if you distribute
-copies of Ghostscript, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must tell them their rights.
-
- Also, for our own protection, we must make certain that everyone finds
-out that there is no warranty for Ghostscript. If Ghostscript is
-modified by someone else and passed on, we want its recipients to know
-that what they have is not what we distributed, so that any problems
-introduced by others will not reflect on our reputation.
-
- Therefore we (Richard M. Stallman and the Free Software Foundation,
-Inc.) make the following terms which say what you must do to be allowed
-to distribute or change Ghostscript.
-
-
- COPYING POLICIES
-
- 1. You may copy and distribute verbatim copies of Ghostscript source
-code as you receive it, in any medium, provided that you conspicuously
-and appropriately publish on each copy a valid copyright and license
-notice "Copyright (C) 1989 Aladdin Enterprises. All rights reserved.
-Distributed by Free Software Foundation, Inc." (or with whatever year is
-appropriate); keep intact the notices on all files that refer to this
-License Agreement and to the absence of any warranty; and give any other
-recipients of the Ghostscript program a copy of this License Agreement
-along with the program. You may charge a distribution fee for the
-physical act of transferring a copy.
-
- 2. You may modify your copy or copies of Ghostscript or any portion of
-it, and copy and distribute such modifications under the terms of
-Paragraph 1 above, provided that you also do the following:
-
- a) cause the modified files to carry prominent notices stating
- that you changed the files and the date of any change; and
-
- b) cause the whole of any work that you distribute or publish,
- that in whole or in part contains or is a derivative of Ghostscript
- or any part thereof, to be licensed at no charge to all third
- parties on terms identical to those contained in this License
- Agreement (except that you may choose to grant more extensive
- warranty protection to some or all third parties, at your option).
-
- c) You may charge a distribution fee for the physical act of
- transferring a copy, and you may at your option offer warranty
- protection in exchange for a fee.
-
-Mere aggregation of another unrelated program with this program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other program under the scope of these terms.
-
- 3. You may copy and distribute Ghostscript (or a portion or derivative
-of it, under Paragraph 2) in object code or executable form under the
-terms of Paragraphs 1 and 2 above provided that you also do one of the
-following:
-
- a) accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- b) accompany it with a written offer, valid for at least three
- years, to give any third party free (except for a nominal
- shipping charge) a complete machine-readable copy of the
- corresponding source code, to be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- c) accompany it with the information you received as to where the
- corresponding source code may be obtained. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form alone.)
-
-For an executable file, complete source code means all the source code for
-all modules it contains; but, as a special exception, it need not include
-source code for modules which are standard libraries that accompany the
-operating system on which the executable file runs.
-
- 4. You may not copy, sublicense, distribute or transfer Ghostscript
-except as expressly provided under this License Agreement. Any attempt
-otherwise to copy, sublicense, distribute or transfer Ghostscript is
-void and your rights to use the program under this License agreement
-shall be automatically terminated. However, parties who have received
-computer software programs from you with this License Agreement will not
-have their licenses terminated so long as such parties remain in full
-compliance.
-
- 5. If you wish to incorporate parts of Ghostscript into other free
-programs whose distribution conditions are different, write to the Free
-Software Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not
-yet worked out a simple rule that can be stated here, but we will often
-permit this. We will be guided by the two goals of preserving the free
-status of all derivatives of our free software and of promoting the
-sharing and reuse of software.
-
-Your comments and suggestions about our licensing policies and our
-software are welcome! Please contact the Free Software Foundation,
-Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.

-
- BECAUSE GHOSTSCRIPT IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
-NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT
-WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD
-M. STALLMAN, ALADDIN ENTERPRISES, L. PETER DEUTSCH, AND/OR OTHER PARTIES
-PROVIDE GHOSTSCRIPT "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
-EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
-WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
-ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF GHOSTSCRIPT IS WITH

- * Usage:
- ansi2knr input_file [output_file]
- * If no output_file is supplied, output goes to stdout.
- * There are no error messages.
- *
- * ansi2knr recognizes function definitions by seeing a non-keyword
- * identifier at the left margin, followed by a left parenthesis,
- * with a right parenthesis as the last character on the line,
- * and with a left brace as the first token on the following line
- * (ignoring possible intervening comments).
- * It will recognize a multi-line header provided that no intervening
- * line ends with a left or right brace or a semicolon.
- * These algorithms ignore whitespace and comments, except that
- * the function name must be the first thing on the line.
- * The following constructs will confuse it:
- * - Any other construct that starts at the left margin and
- * follows the above syntax (such as a macro or function call).
- * - Some macros that tinker with the syntax of the function header.

- * The original and principal author of ansi2knr is L. Peter Deutsch
- * <ghost@aladdin.com>. Other authors are noted in the change history
- * that follows (in reverse chronological order):
- lpd 96-01-21 added code to cope with not HAVE_CONFIG_H and with
- compilers that don't understand void, as suggested by
- Tom Lane
- lpd 96-01-15 changed to require that the first non-comment token
- on the line following a function header be a left brace,
- to reduce sensitivity to macros, as suggested by Tom Lane
- <tgl@sss.pgh.pa.us>
- lpd 95-06-22 removed #ifndefs whose sole purpose was to define
- undefined preprocessor symbols as 0; changed all #ifdefs
- for configuration symbols to #ifs
- lpd 95-04-05 changed copyright notice to make it clear that
- including ansi2knr in a program does not bring the entire
- program under the GPL
- lpd 94-12-18 added conditionals for systems where ctype macros
- don't handle 8-bit characters properly, suggested by
- Francois Pinard <pinard@iro.umontreal.ca>;
- removed --varargs switch (this is now the default)
- lpd 94-10-10 removed CONFIG_BROKETS conditional
- lpd 94-07-16 added some conditionals to help GNU `configure',
- suggested by Francois Pinard <pinard@iro.umontreal.ca>;
- properly erase prototype args in function parameters,
- contributed by Jim Avera <jima@netcom.com>;
- correct error in writeblanks (it shouldn't erase EOLs)

- * This is a fast-and-accurate implementation of inverse Discrete Cosine
- * Transform (IDCT) for ARMv6+. It also performs dequantization of the input
- * coefficients just like other methods.
- *
- * This implementation is based on the scaled 1-D DCT algorithm proposed by
- * Arai, Agui, and Nakajima. The following code is based on the figure 4-8
- * on page 52 of the JPEG textbook by Pennebaker and Mitchell. Coefficients
- * are (almost) directly mapped into registers.
- *
- * The accuracy is achieved by using SMULWy and SMLAWy instructions. Both
- * multiply 32 bits by 16 bits and store the top 32 bits of the result. It
- * makes 32-bit fixed-point arithmetic possible without overflow. That is
- * why jpeg_idct_ifast(), which is written in C, cannot be improved.
- *
- * More tricks are used to gain more speed. First of all, we use as many
- * registers as possible. ARM processor has 16 registers including sp (r13)
- * and pc (r15), so only 14 registers can be used without limitations. In
- * general, we let r0 to r7 hold the coefficients; r10 and r11 hold four
- * 16-bit constants; r12 and r14 hold two of the four arguments; and r8 hold
- * intermediate value. In the second pass, r9 is the loop counter. In the
- * first pass, r8 to r11 are used to hold quantization values, so the loop
- * counter is held by sp. Yes, the stack pointer. Since it must be aligned
- * to 4-byte boundary all the time, we align it to 32-byte boundary and use
- * bit 3 to bit 5. As the result, we actually use 14.1 registers. :-)
- *
- * Second, we rearrange quantization values to access them sequentially. The
- * table is first transposed, and the new columns are placed in the order of
- * 7, 5, 1, 3, 0, 2, 4, 6. Thus we can use LDMDB to load four values at a
- * time. Rearranging coefficients also helps, but that requires to change a
- * dozen of files, which seems not worth it. In addition, we choose to scale
- * up quantization values by 13 bits, so the coefficients are scaled up by
- * 16 bits after both passes. Then we can pack and saturate them two at a
- * time using PKHTB and USAT16 instructions.
- *
- * Third, we reorder the instructions to avoid bubbles in the pipeline. This
- * is done by hand accroding to the cycle timings and the interlock behavior
- * described in the technical reference manual of ARM1136JF-S. We also take
- * advantage of dual issue processors by interleaving instructions with
- * dependencies. It has been benchmarked on four devices and all the results
- * showed distinguishable improvements. Note that PLD instructions actually
- * slow things down, so they are removed at the last minute. In the future,
- * this might be futher improved using a system profiler.

-@ NOTES :
-@
-@ It was tested to be IEEE 1180 compliant. Since IEEE 1180 compliance is more stringent
-@ than MPEG-4 compliance, this version is also MPEG-4 compliant.
-@
-@ CODE STRUCTURE:
-@ (i) Macros for transposing an 8x8 matrix and for configuring the VFP unit are defined.
-@ (ii) Macro for IDCT in one dimension is defined as four stages
-@ (iii) The two dimensional code begins
-@ (iv) constants are defined in the area DataArea
-@
-@ PROGRAM FLOW:
-@
-@ The VFP is configured
-@ The parameters to IDCT are loaded
-@ the coefficients are loaded
-@ loop:
-@ decrement loop counter
-@ The first input Matrix is loaded and pre-scaled
-@ The input is prescaled using the constants
-@ IDCT is performed in one dimension on the 8 columns
-@ The matrix is transposed
-@ A bias is loaded an added to the matrix
-@ IDCT is performed in one dimension on the 8 rows
-@ The matrix is post-scaled
-@ The matrix is saved
-@ test loop counter and loop if greater than zero

-CHANGE LOG for Independent JPEG Group's JPEG software
-
-
-Version 6b 27-Mar-1998
------------------------
-
-jpegtran has new features for lossless image transformations (rotation
-and flipping) as well as "lossless" reduction to grayscale.
-
-jpegtran now copies comments by default; it has a -copy switch to enable
-copying all APPn blocks as well, or to suppress comments. (Formerly it
-always suppressed comments and APPn blocks.) jpegtran now also preserves
-JFIF version and resolution information.
-
-New decompressor library feature: COM and APPn markers found in the input
-file can be saved in memory for later use by the application. (Before,
-you had to code this up yourself with a custom marker processor.)
-
-There is an unused field "void * client_data" now in compress and decompress
-parameter structs; this may be useful in some applications.
-
-JFIF version number information is now saved by the decoder and accepted by
-the encoder. jpegtran uses this to copy the source file's version number,
-to ensure "jpegtran -copy all" won't create bogus files that contain JFXX
-extensions but claim to be version 1.01. Applications that generate their
-own JFXX extension markers also (finally) have a supported way to cause the
-encoder to emit JFIF version number 1.02.
-
-djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather
-than as unknown APP0 markers.
-
-In -verbose mode, djpeg and rdjpgcom will try to print the contents of
-APP12 markers as text. Some digital cameras store useful text information
-in APP12 markers.
-
-Handling of truncated data streams is more robust: blocks beyond the one in
-which the error occurs will be output as uniform gray, or left unchanged
-if decoding a progressive JPEG. The appearance no longer depends on the
-Huffman tables being used.
-
-Huffman tables are checked for validity much more carefully than before.
-
-To avoid the Unisys LZW patent, djpeg's GIF output capability has been
-changed to produce "uncompressed GIFs", and cjpeg's GIF input capability
-has been removed altogether. We're not happy about it either, but there
-seems to be no good alternative.
-
-The configure script now supports building libjpeg as a shared library
-on many flavors of Unix (all the ones that GNU libtool knows how to
-build shared libraries for). Use "./configure --enable-shared" to
-try this out.
-
-New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio.
-Also, a jconfig file and a build script for Metrowerks CodeWarrior
-on Apple Macintosh. makefile.dj has been updated for DJGPP v2, and there
-are miscellaneous other minor improvements in the makefiles.
-
-jmemmac.c now knows how to create temporary files following Mac System 7
-conventions.
-
-djpeg's -map switch is now able to read raw-format PPM files reliably.
-
-cjpeg -progressive -restart no longer generates any unnecessary DRI markers.
-
-Multiple calls to jpeg_simple_progression for a single JPEG object
-no longer leak memory.
-
-
-Version 6a 7-Feb-96
---------------------
-
-Library initialization sequence modified to detect version mismatches
-and struct field packing mismatches between library and calling application.
-This change requires applications to be recompiled, but does not require
-any application source code change.
-
-All routine declarations changed to the style "GLOBAL(type) name ...",
-that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the
-routine's return type as an argument. This makes it possible to add
-Microsoft-style linkage keywords to all the routines by changing just
-these macros. Note that any application code that was using these macros
-will have to be changed.
-
-DCT coefficient quantization tables are now stored in normal array order
-rather than zigzag order. Application code that calls jpeg_add_quant_table,
-or otherwise manipulates quantization tables directly, will need to be
-changed. If you need to make such code work with either older or newer
-versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is
-recommended.
-
-djpeg's trace capability now dumps DQT tables in natural order, not zigzag
-order. This allows the trace output to be made into a "-qtables" file
-more easily.
-
-New system-dependent memory manager module for use on Apple Macintosh.
-
-Fix bug in cjpeg's -smooth option: last one or two scanlines would be
-duplicates of the prior line unless the image height mod 16 was 1 or 2.
-
-Repair minor problems in VMS, BCC, MC6 makefiles.
-
-New configure script based on latest GNU Autoconf.
-
-Correct the list of include files needed by MetroWerks C for ccommand().
-
-Numerous small documentation updates.
-
-
-Version 6 2-Aug-95
--------------------
-
-Progressive JPEG support: library can read and write full progressive JPEG
-files. A "buffered image" mode supports incremental decoding for on-the-fly
-display of progressive images. Simply recompiling an existing IJG-v5-based
-decoder with v6 should allow it to read progressive files, though of course
-without any special progressive display.
-
-New "jpegtran" application performs lossless transcoding between different
-JPEG formats; primarily, it can be used to convert baseline to progressive
-JPEG and vice versa. In support of jpegtran, the library now allows lossless
-reading and writing of JPEG files as DCT coefficient arrays. This ability
-may be of use in other applications.
-
-Notes for programmers:
-* We changed jpeg_start_decompress() to be able to suspend; this makes all
-decoding modes available to suspending-input applications. However,
-existing applications that use suspending input will need to be changed
-to check the return value from jpeg_start_decompress(). You don't need to
-do anything if you don't use a suspending data source.
-* We changed the interface to the virtual array routines: access_virt_array
-routines now take a count of the number of rows to access this time. The
-last parameter to request_virt_array routines is now interpreted as the
-maximum number of rows that may be accessed at once, but not necessarily
-the height of every access.
-
-
-Version 5b 15-Mar-95
----------------------
-
-Correct bugs with grayscale images having v_samp_factor > 1.
-
-jpeg_write_raw_data() now supports output suspension.
-
-Correct bugs in "configure" script for case of compiling in
-a directory other than the one containing the source files.
-
-Repair bug in jquant1.c: sometimes didn't use as many colors as it could.
-
-Borland C makefile and jconfig file work under either MS-DOS or OS/2.
-
-Miscellaneous improvements to documentation.
-
-
-Version 5a 7-Dec-94
---------------------
-
-Changed color conversion roundoff behavior so that grayscale values are
-represented exactly. (This causes test image files to change.)
-
-Make ordered dither use 16x16 instead of 4x4 pattern for a small quality
-improvement.
-
-New configure script based on latest GNU Autoconf.
-Fix configure script to handle CFLAGS correctly.
-Rename *.auto files to *.cfg, so that configure script still works if
-file names have been truncated for DOS.
-
-Fix bug in rdbmp.c: didn't allow for extra data between header and image.
-
-Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data.
-
-Fix several bugs in rdrle.c.
-
-NEED_SHORT_EXTERNAL_NAMES option was broken.
-
-Revise jerror.h/jerror.c for more flexibility in message table.
-
-Repair oversight in jmemname.c NO_MKTEMP case: file could be there
-but unreadable.
-
-
-Version 5 24-Sep-94
---------------------
-
-Version 5 represents a nearly complete redesign and rewrite of the IJG
-software. Major user-visible changes include:
- * Automatic configuration simplifies installation for most Unix systems.
- * A range of speed vs. image quality tradeoffs are supported.
- This includes resizing of an image during decompression: scaling down
- by a factor of 1/2, 1/4, or 1/8 is handled very efficiently.
- * New programs rdjpgcom and wrjpgcom allow insertion and extraction
- of text comments in a JPEG file.
-
-The application programmer's interface to the library has changed completely.
-Notable improvements include:
- * We have eliminated the use of callback routines for handling the
- uncompressed image data. The application now sees the library as a
- set of routines that it calls to read or write image data on a
- scanline-by-scanline basis.
- * The application image data is represented in a conventional interleaved-
- pixel format, rather than as a separate array for each color channel.
- This can save a copying step in many programs.
- * The handling of compressed data has been cleaned up: the application can
- supply routines to source or sink the compressed data. It is possible to
- suspend processing on source/sink buffer overrun, although this is not
- supported in all operating modes.
- * All static state has been eliminated from the library, so that multiple
- instances of compression or decompression can be active concurrently.
- * JPEG abbreviated datastream formats are supported, ie, quantization and
- Huffman tables can be stored separately from the image data.
- * And not only that, but the documentation of the library has improved
- considerably!
-
-
-The last widely used release before the version 5 rewrite was version 4A of
-18-Feb-93. Change logs before that point have been discarded, since they
-are not of much interest after the rewrite.

-.TH CJPEG 1 "20 March 1998"
-.SH NAME
-cjpeg \- compress an image file to a JPEG file
-.SH SYNOPSIS
-.B cjpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B cjpeg
-compresses the named image file, or the standard input if no file is
-named, and produces a JPEG/JFIF file on the standard output.
-The currently supported input file formats are: PPM (PBMPLUS color
-format), PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster
-Toolkit format). (RLE is supported only if the URT library is available.)
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-quality " N"
-Scale quantization tables to adjust image quality. Quality is 0 (worst) to
-100 (best); default is 75. (See below for more info.)
-.TP
-.B \-grayscale
-Create monochrome JPEG file from color input. Be sure to use this switch when
-compressing a grayscale BMP file, because
-.B cjpeg
-isn't bright enough to notice whether a BMP file uses only shades of gray.
-By saying
-.BR \-grayscale ,
-you'll get a smaller JPEG file that takes less time to process.
-.TP
-.B \-optimize
-Perform optimization of entropy encoding parameters. Without this, default
-encoding parameters are used.
-.B \-optimize
-usually makes the JPEG file a little smaller, but
-.B cjpeg
-runs somewhat slower and needs much more memory. Image quality and speed of
-decompression are unaffected by
-.BR \-optimize .
-.TP
-.B \-progressive
-Create progressive JPEG file (see below).
-.TP
-.B \-targa
-Input file is Targa format. Targa files that contain an "identification"
-field will not be automatically recognized by
-.BR cjpeg ;
-for such files you must specify
-.B \-targa
-to make
-.B cjpeg
-treat the input as Targa format.
-For most Targa files, you won't need this switch.
-.PP
-The
-.B \-quality
-switch lets you trade off compressed file size against quality of the
-reconstructed image: the higher the quality setting, the larger the JPEG file,
-and the closer the output image will be to the original input. Normally you
-want to use the lowest quality setting (smallest file) that decompresses into
-something visually indistinguishable from the original image. For this
-purpose the quality setting should be between 50 and 95; the default of 75 is
-often about right. If you see defects at
-.B \-quality
-75, then go up 5 or 10 counts at a time until you are happy with the output
-image. (The optimal setting will vary from one image to another.)
-.PP
-.B \-quality
-100 will generate a quantization table of all 1's, minimizing loss in the
-quantization step (but there is still information loss in subsampling, as well
-as roundoff error). This setting is mainly of interest for experimental
-purposes. Quality values above about 95 are
-.B not
-recommended for normal use; the compressed file size goes up dramatically for
-hardly any gain in output image quality.
-.PP
-In the other direction, quality values below 50 will produce very small files
-of low image quality. Settings around 5 to 10 might be useful in preparing an
-index of a large image library, for example. Try
-.B \-quality
-2 (or so) for some amusing Cubist effects. (Note: quality
-values below about 25 generate 2-byte quantization tables, which are
-considered optional in the JPEG standard.
-.B cjpeg
-emits a warning message when you give such a quality value, because some
-other JPEG programs may be unable to decode the resulting file. Use
-.B \-baseline
-if you need to ensure compatibility at low quality values.)
-.PP
-The
-.B \-progressive
-switch creates a "progressive JPEG" file. In this type of JPEG file, the data
-is stored in multiple scans of increasing quality. If the file is being
-transmitted over a slow communications link, the decoder can use the first
-scan to display a low-quality image very quickly, and can then improve the
-display with each subsequent scan. The final image is exactly equivalent to a
-standard JPEG file of the same quality setting, and the total file size is
-about the same --- often a little smaller.
-.B Caution:
-progressive JPEG is not yet widely implemented, so many decoders will be
-unable to view a progressive JPEG file at all.
-.PP
-Switches for advanced users:
-.TP
-.B \-dct int
-Use integer DCT method (default).
-.TP
-.B \-dct fast
-Use fast integer DCT (less accurate).
-.TP
-.B \-dct float
-Use floating-point DCT method.
-The float method is very slightly more accurate than the int method, but is
-much slower unless your machine has very fast floating-point hardware. Also
-note that results of the floating-point method may vary slightly across
-machines, while the integer methods should give the same results everywhere.
-The fast integer method is much less accurate than the other two.
-.TP
-.BI \-restart " N"
-Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
-attached to the number.
-.B \-restart 0
-(the default) means no restart markers.
-.TP
-.BI \-smooth " N"
-Smooth the input image to eliminate dithering noise. N, ranging from 1 to
-100, indicates the strength of smoothing. 0 (the default) means no smoothing.
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images. Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number. For example,
-.B \-max 4m
-selects 4000000 bytes. If more space is needed, temporary files will be used.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.B \-verbose
-Enable debug printout. More
-.BR \-v 's
-give more output. Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.PP
-The
-.B \-restart
-option inserts extra markers that allow a JPEG decoder to resynchronize after
-a transmission error. Without restart markers, any damage to a compressed
-file will usually ruin the image from the point of the error to the end of the
-image; with restart markers, the damage is usually confined to the portion of
-the image up to the next restart marker. Of course, the restart markers
-occupy extra space. We recommend
-.B \-restart 1
-for images that will be transmitted across unreliable networks such as Usenet.
-.PP
-The
-.B \-smooth
-option filters the input to eliminate fine-scale noise. This is often useful
-when converting dithered images to JPEG: a moderate smoothing factor of 10 to
-50 gets rid of dithering patterns in the input file, resulting in a smaller
-JPEG file and a better-looking image. Too large a smoothing factor will
-visibly blur the image, however.
-.PP
-Switches for wizards:
-.TP
-.B \-baseline
-Force baseline-compatible quantization tables to be generated. This clamps
-quantization values to 8 bits even at low quality settings. (This switch is
-poorly named, since it does not ensure that the output is actually baseline
-JPEG. For example, you can use
-.B \-baseline
-and
-.B \-progressive
-together.)
-.TP
-.BI \-qtables " file"
-Use the quantization tables given in the specified text file.
-.TP
-.BI \-qslots " N[,...]"
-Select which quantization table to use for each color component.
-.TP
-.BI \-sample " HxV[,...]"
-Set JPEG sampling factors for each color component.
-.TP
-.BI \-scans " file"
-Use the scan script given in the specified text file.
-.PP
-The "wizard" switches are intended for experimentation with JPEG. If you
-don't know what you are doing, \fBdon't use them\fR. These switches are
-documented further in the file wizard.doc.
-.SH EXAMPLES
-.LP
-This example compresses the PPM file foo.ppm with a quality factor of
-60 and saves the output as foo.jpg:
-.IP
-.B cjpeg \-quality
-.I 60 foo.ppm
-.B >
-.I foo.jpg
-.SH HINTS
-Color GIF files are not the ideal input for JPEG; JPEG is really intended for
-compressing full-color (24-bit) images. In particular, don't try to convert
-cartoons, line drawings, and other images that have only a few distinct
-colors. GIF works great on these, JPEG does not. If you want to convert a
-GIF to JPEG, you should experiment with
-.BR cjpeg 's
-.B \-quality
-and
-.B \-smooth
-options to get a satisfactory conversion.
-.B \-smooth 10
-or so is often helpful.
-.PP
-Avoid running an image through a series of JPEG compression/decompression
-cycles. Image quality loss will accumulate; after ten or so cycles the image
-may be noticeably worse than it was after one cycle. It's best to use a
-lossless format while manipulating an image, then convert to JPEG format when
-you are ready to file the image away.
-.PP
-The
-.B \-optimize
-option to
-.B cjpeg
-is worth using when you are making a "final" version for posting or archiving.
-It's also a win when you are using low quality settings to make very small
-JPEG files; the percentage improvement is often a lot more than it is on
-larger files. (At present,
-.B \-optimize
-mode is always selected when generating progressive JPEG files.)
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.SH AUTHOR
-Independent JPEG Group
-.SH BUGS
-Arithmetic coding is not supported for legal reasons.
-.PP
-GIF input files are no longer supported, to avoid the Unisys LZW patent.
-Use a Unisys-licensed program if you need to read a GIF file. (Conversion
-of GIF files to JPEG is usually a bad idea anyway.)
-.PP
-Not all variants of BMP and Targa file formats are supported.
-.PP
-The
-.B \-targa
-switch is not a bug, it's a feature. (It would be a bug if the Targa format
-designers had not been clueless.)
-.PP
-Still not as fast as we'd like.

-IJG JPEG LIBRARY: CODING RULES
-
-Copyright (C) 1991-1996, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Since numerous people will be contributing code and bug fixes, it's important
-to establish a common coding style. The goal of using similar coding styles
-is much more important than the details of just what that style is.
-
-In general we follow the recommendations of "Recommended C Style and Coding
-Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
-Brader). This document is available in the IJG FTP archive (see
-jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
-
-Block comments should be laid out thusly:
-
-/*
- * Block comments in this style.
- */
-
-We indent statements in K&R style, e.g.,
- if (test) {
- then-part;
- } else {
- else-part;
- }
-with two spaces per indentation level. (This indentation convention is
-handled automatically by GNU Emacs and many other text editors.)
-
-Multi-word names should be written in lower case with underscores, e.g.,
-multi_word_name (not multiWordName). Preprocessor symbols and enum constants
-are similar but upper case (MULTI_WORD_NAME). Names should be unique within
-the first fifteen characters. (On some older systems, global names must be
-unique within six characters. We accommodate this without cluttering the
-source code by using macros to substitute shorter names.)
-
-We use function prototypes everywhere; we rely on automatic source code
-transformation to feed prototype-less C compilers. Transformation is done
-by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
-ansi2knr is not very bright, so it imposes a format requirement on function
-declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions
-should be written in the following style:
-
-LOCAL(int *)
-function_name (int a, char *b)
-{
- code...
-}
-
-Note that each function definition must begin with GLOBAL(type), LOCAL(type),
-or METHODDEF(type). These macros expand to "static type" or just "type" as
-appropriate. They provide a readable indication of the routine's usage and
-can readily be changed for special needs. (For instance, special linkage
-keywords can be inserted for use in Windows DLLs.)
-
-ansi2knr does not transform method declarations (function pointers in
-structs). We handle these with a macro JMETHOD, defined as
- #ifdef HAVE_PROTOTYPES
- #define JMETHOD(type,methodname,arglist) type (*methodname) arglist
- #else
- #define JMETHOD(type,methodname,arglist) type (*methodname) ()
- #endif
-which is used like this:
- struct function_pointers {
- JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
- JMETHOD(void, term_entropy_encoder, (void));
- };
-Note the set of parentheses surrounding the parameter list.
-
-A similar solution is used for forward and external function declarations
-(see the EXTERN and JPP macros).
-
-If the code is to work on non-ANSI compilers, we cannot rely on a prototype
-declaration to coerce actual parameters into the right types. Therefore, use
-explicit casts on actual parameters whenever the actual parameter type is not
-identical to the formal parameter. Beware of implicit conversions to "int".
-
-It seems there are some non-ANSI compilers in which the sizeof() operator
-is defined to return int, yet size_t is defined as long. Needless to say,
-this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(),
-so that the result is guaranteed to be of type size_t.
-
-
-The JPEG library is intended to be used within larger programs. Furthermore,
-we want it to be reentrant so that it can be used by applications that process
-multiple images concurrently. The following rules support these requirements:
-
-1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
-pass these through the common routines provided.
-
-2. Minimize global namespace pollution. Functions should be declared static
-wherever possible. (Note that our method-based calling conventions help this
-a lot: in many modules only the initialization function will ever need to be
-called directly, so only that function need be externally visible.) All
-global function names should begin with "jpeg_", and should have an
-abbreviated name (unique in the first six characters) substituted by macro
-when NEED_SHORT_EXTERNAL_NAMES is set.
-
-3. Don't use global variables; anything that must be used in another module
-should be in the common data structures.
-
-4. Don't use static variables except for read-only constant tables. Variables
-that should be private to a module can be placed into private structures (see
-the system architecture document, structure.doc).
-
-5. Source file names should begin with "j" for files that are part of the
-library proper; source files that are not part of the library, such as cjpeg.c
-and djpeg.c, do not begin with "j". Keep source file names to eight
-characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep
-compression and decompression code in separate source files --- some
-applications may want only one half of the library.
-
-Note: these rules (particularly #4) are not followed religiously in the
-modules that are used in cjpeg/djpeg but are not part of the JPEG library
-proper. Those modules are not really intended to be used in other
-applications.

-.TH DJPEG 1 "22 August 1997"
-.SH NAME
-djpeg \- decompress a JPEG file to an image file
-.SH SYNOPSIS
-.B djpeg
-[
-.I options
-]
-[
-.I filename
-]
-.LP
-.SH DESCRIPTION
-.LP
-.B djpeg
-decompresses the named JPEG file, or the standard input if no file is named,
-and produces an image file on the standard output. PBMPLUS (PPM/PGM), BMP,
-GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected.
-(RLE is supported only if the URT library is available.)
-.SH OPTIONS
-All switch names may be abbreviated; for example,
-.B \-grayscale
-may be written
-.B \-gray
-or
-.BR \-gr .
-Most of the "basic" switches can be abbreviated to as little as one letter.
-Upper and lower case are equivalent (thus
-.B \-BMP
-is the same as
-.BR \-bmp ).
-British spellings are also accepted (e.g.,
-.BR \-greyscale ),
-though for brevity these are not mentioned below.
-.PP
-The basic switches are:
-.TP
-.BI \-colors " N"
-Reduce image to at most N colors. This reduces the number of colors used in
-the output image, so that it can be displayed on a colormapped display or
-stored in a colormapped file format. For example, if you have an 8-bit
-display, you'd need to reduce to 256 or fewer colors.
-.TP
-.BI \-quantize " N"
-Same as
-.BR \-colors .
-.B \-colors
-is the recommended name,
-.B \-quantize
-is provided only for backwards compatibility.
-.TP
-.B \-fast
-Select recommended processing options for fast, low quality output. (The
-default options are chosen for highest quality output.) Currently, this is
-equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.
-.TP
-.B \-grayscale
-Force gray-scale output even if JPEG file is color. Useful for viewing on
-monochrome displays; also,
-.B djpeg
-runs noticeably faster in this mode.
-.TP
-.BI \-scale " M/N"
-Scale the output image by a factor M/N. Currently the scale factor must be
-1/1, 1/2, 1/4, or 1/8. Scaling is handy if the image is larger than your
-screen; also,
-.B djpeg
-runs much faster when scaling down the output.
-.TP
-.B \-bmp
-Select BMP output format (Windows flavor). 8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-gif
-Select GIF output format. Since GIF does not support more than 256 colors,
-.B \-colors 256
-is assumed (unless you specify a smaller number of colors).
-.TP
-.B \-os2
-Select BMP output format (OS/2 1.x flavor). 8-bit colormapped format is
-emitted if
-.B \-colors
-or
-.B \-grayscale
-is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
-format is emitted.
-.TP
-.B \-pnm
-Select PBMPLUS (PPM/PGM) output format (this is the default format).
-PGM is emitted if the JPEG file is gray-scale or if
-.B \-grayscale
-is specified; otherwise PPM is emitted.
-.TP
-.B \-rle
-Select RLE output format. (Requires URT library.)
-.TP
-.B \-targa
-Select Targa output format. Gray-scale format is emitted if the JPEG file is
-gray-scale or if
-.B \-grayscale
-is specified; otherwise, colormapped format is emitted if
-.B \-colors
-is specified; otherwise, 24-bit full-color format is emitted.
-.PP
-Switches for advanced users:
-.TP
-.B \-dct int
-Use integer DCT method (default).
-.TP
-.B \-dct fast
-Use fast integer DCT (less accurate).
-.TP
-.B \-dct float
-Use floating-point DCT method.
-The float method is very slightly more accurate than the int method, but is
-much slower unless your machine has very fast floating-point hardware. Also
-note that results of the floating-point method may vary slightly across
-machines, while the integer methods should give the same results everywhere.
-The fast integer method is much less accurate than the other two.
-.TP
-.B \-dither fs
-Use Floyd-Steinberg dithering in color quantization.
-.TP
-.B \-dither ordered
-Use ordered dithering in color quantization.
-.TP
-.B \-dither none
-Do not use dithering in color quantization.
-By default, Floyd-Steinberg dithering is applied when quantizing colors; this
-is slow but usually produces the best results. Ordered dither is a compromise
-between speed and quality; no dithering is fast but usually looks awful. Note
-that these switches have no effect unless color quantization is being done.
-Ordered dither is only available in
-.B \-onepass
-mode.
-.TP
-.BI \-map " file"
-Quantize to the colors used in the specified image file. This is useful for
-producing multiple files with identical color maps, or for forcing a
-predefined set of colors to be used. The
-.I file
-must be a GIF or PPM file. This option overrides
-.B \-colors
-and
-.BR \-onepass .
-.TP
-.B \-nosmooth
-Use a faster, lower-quality upsampling routine.
-.TP
-.B \-onepass
-Use one-pass instead of two-pass color quantization. The one-pass method is
-faster and needs less memory, but it produces a lower-quality image.
-.B \-onepass
-is ignored unless you also say
-.B \-colors
-.IR N .
-Also, the one-pass method is always used for gray-scale output (the two-pass
-method is no improvement then).
-.TP
-.BI \-maxmemory " N"
-Set limit for amount of memory to use in processing large images. Value is
-in thousands of bytes, or millions of bytes if "M" is attached to the
-number. For example,
-.B \-max 4m
-selects 4000000 bytes. If more space is needed, temporary files will be used.
-.TP
-.BI \-outfile " name"
-Send output image to the named file, not to standard output.
-.TP
-.B \-verbose
-Enable debug printout. More
-.BR \-v 's
-give more output. Also, version information is printed at startup.
-.TP
-.B \-debug
-Same as
-.BR \-verbose .
-.SH EXAMPLES
-.LP
-This example decompresses the JPEG file foo.jpg, quantizes it to
-256 colors, and saves the output in 8-bit BMP format in foo.bmp:
-.IP
-.B djpeg \-colors 256 \-bmp
-.I foo.jpg
-.B >
-.I foo.bmp
-.SH HINTS
-To get a quick preview of an image, use the
-.B \-grayscale
-and/or
-.B \-scale
-switches.
-.B \-grayscale \-scale 1/8
-is the fastest case.
-.PP
-Several options are available that trade off image quality to gain speed.
-.B \-fast
-turns on the recommended settings.
-.PP
-.B \-dct fast
-and/or
-.B \-nosmooth
-gain speed at a small sacrifice in quality.
-When producing a color-quantized image,
-.B \-onepass \-dither ordered
-is fast but much lower quality than the default behavior.
-.B \-dither none
-may give acceptable results in two-pass mode, but is seldom tolerable in
-one-pass mode.
-.PP
-If you are fortunate enough to have very fast floating point hardware,
-\fB\-dct float\fR may be even faster than \fB\-dct fast\fR. But on most
-machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is
-not worth using, because its theoretical accuracy advantage is too small to be
-significant in practice.
-.SH ENVIRONMENT
-.TP
-.B JPEGMEM
-If this environment variable is set, its value is the default memory limit.
-The value is specified as described for the
-.B \-maxmemory
-switch.
-.B JPEGMEM
-overrides the default value specified when the program was compiled, and
-itself is overridden by an explicit
-.BR \-maxmemory .

-.SH AUTHOR
-Independent JPEG Group
-.SH BUGS
-Arithmetic coding is not supported for legal reasons.
-.PP
-To avoid the Unisys LZW patent,
-.B djpeg
-produces uncompressed GIF files. These are larger than they should be, but
-are readable by standard GIF decoders.
-.PP
-Still not as fast as we'd like.

- *
- * This file contains a command-line user interface for the JPEG decompressor.
- * It should work on any system with Unix- or MS-DOS-style command lines.
- *
- * Two different command line styles are permitted, depending on the
- * compile-time switch TWO_FILE_COMMANDLINE:
- * djpeg [options] inputfile outputfile
- * djpeg [options] [inputfile]
- * In the second style, output is always to standard output, which you'd
- * normally redirect to a file or pipe to some other program. Input is
- * either from a named file or from standard input (typically redirected).
- * The second style is convenient on Unix but is unhelpful on systems that
- * don't support pipes. Also, you MUST use the first style if your system
- * doesn't do binary I/O to stdin/stdout.
- * To simplify script writing, the "-outfile" switch is provided. The syntax
- * djpeg [options] -outfile outputfile inputfile
- * works regardless of which command line style is used.

- * On some systems you may need to set up a signal handler to ensure that
- * temporary files are deleted if the program is interrupted. See libjpeg.doc.
- *
- * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
- * files to be compatible with everyone else's. If you cannot readily read
- * your data in that order, you'll need an intermediate array to hold the

- * error_exit routine. To do this, we make a private extension of the
- * standard JPEG error handler object. (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)

- * We cheated a bit by calling alloc_sarray() after jpeg_start_decompress();
- * we should have done it beforehand to ensure that the space would be
- * counted against the JPEG max_memory setting. In some systems the above
- * code would risk an out-of-memory error. However, in general we don't
- * know the output image dimensions before jpeg_start_decompress(), unless we
- * call jpeg_calc_output_dimensions(). See libjpeg.doc for more about this.
- *
- * Scanlines are returned in the same order as they appear in the JPEG file,
- * which is standardly top-to-bottom. If you must emit data bottom-to-top,
- * you can use one of the virtual arrays provided by the JPEG memory manager
- * to invert the data. See wrbmp.c for an example.
- *
- * As with compression, some operating modes may require temporary files.
- * On some systems you may need to set up a signal handler to ensure that
- * temporary files are deleted if the program is interrupted. See libjpeg.doc.

-IJG JPEG LIBRARY: FILE LIST
-
-Copyright (C) 1994-1998, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Here is a road map to the files in the IJG JPEG distribution. The
-distribution includes the JPEG library proper, plus two application
-programs ("cjpeg" and "djpeg") which use the library to convert JPEG
-files to and from some other popular image formats. A third application
-"jpegtran" uses the library to do lossless conversion between different
-variants of JPEG. There are also two stand-alone applications,
-"rdjpgcom" and "wrjpgcom".
-
-
-THE JPEG LIBRARY
-================
-
-Include files:
-
-jpeglib.h JPEG library's exported data and function declarations.
-jconfig.h Configuration declarations. Note: this file is not present
- in the distribution; it is generated during installation.
-jmorecfg.h Additional configuration declarations; need not be changed
- for a standard installation.
-jerror.h Declares JPEG library's error and trace message codes.
-jinclude.h Central include file used by all IJG .c files to reference
- system include files.
-jpegint.h JPEG library's internal data structures.
-jchuff.h Private declarations for Huffman encoder modules.
-jdhuff.h Private declarations for Huffman decoder modules.
-jdct.h Private declarations for forward & reverse DCT subsystems.
-jmemsys.h Private declarations for memory management subsystem.
-jversion.h Version information.
-
-Applications using the library should include jpeglib.h (which in turn
-includes jconfig.h and jmorecfg.h). Optionally, jerror.h may be included
-if the application needs to reference individual JPEG error codes. The
-other include files are intended for internal use and would not normally
-be included by an application program. (cjpeg/djpeg/etc do use jinclude.h,
-since its function is to improve portability of the whole IJG distribution.
-Most other applications will directly include the system include files they
-want, and hence won't need jinclude.h.)
-
-
-C source code files:
-
-These files contain most of the functions intended to be called directly by
-an application program:
-
-jcapimin.c Application program interface: core routines for compression.
-jcapistd.c Application program interface: standard compression.
-jdapimin.c Application program interface: core routines for decompression.
-jdapistd.c Application program interface: standard decompression.
-jcomapi.c Application program interface routines common to compression
- and decompression.
-jcparam.c Compression parameter setting helper routines.
-jctrans.c API and library routines for transcoding compression.
-jdtrans.c API and library routines for transcoding decompression.
-
-Compression side of the library:
-
-jcinit.c Initialization: determines which other modules to use.
-jcmaster.c Master control: setup and inter-pass sequencing logic.
-jcmainct.c Main buffer controller (preprocessor => JPEG compressor).
-jcprepct.c Preprocessor buffer controller.
-jccoefct.c Buffer controller for DCT coefficient buffer.
-jccolor.c Color space conversion.
-jcsample.c Downsampling.
-jcdctmgr.c DCT manager (DCT implementation selection & control).
-jfdctint.c Forward DCT using slow-but-accurate integer method.
-jfdctfst.c Forward DCT using faster, less accurate integer method.
-jfdctflt.c Forward DCT using floating-point arithmetic.
-jchuff.c Huffman entropy coding for sequential JPEG.
-jcphuff.c Huffman entropy coding for progressive JPEG.
-jcmarker.c JPEG marker writing.
-jdatadst.c Data destination manager for stdio output.
-
-Decompression side of the library:
-
-jdmaster.c Master control: determines which other modules to use.
-jdinput.c Input controller: controls input processing modules.
-jdmainct.c Main buffer controller (JPEG decompressor => postprocessor).
-jdcoefct.c Buffer controller for DCT coefficient buffer.
-jdpostct.c Postprocessor buffer controller.
-jdmarker.c JPEG marker reading.
-jdhuff.c Huffman entropy decoding for sequential JPEG.
-jdphuff.c Huffman entropy decoding for progressive JPEG.
-jddctmgr.c IDCT manager (IDCT implementation selection & control).
-jidctint.c Inverse DCT using slow-but-accurate integer method.
-jidctfst.c Inverse DCT using faster, less accurate integer method.
-jidctflt.c Inverse DCT using floating-point arithmetic.
-jidctred.c Inverse DCTs with reduced-size outputs.
-jdsample.c Upsampling.
-jdcolor.c Color space conversion.
-jdmerge.c Merged upsampling/color conversion (faster, lower quality).
-jquant1.c One-pass color quantization using a fixed-spacing colormap.
-jquant2.c Two-pass color quantization using a custom-generated colormap.
- Also handles one-pass quantization to an externally given map.
-jdatasrc.c Data source manager for stdio input.
-
-Support files for both compression and decompression:
-
-jerror.c Standard error handling routines (application replaceable).
-jmemmgr.c System-independent (more or less) memory management code.
-jutils.c Miscellaneous utility routines.
-
-jmemmgr.c relies on a system-dependent memory management module. The IJG
-distribution includes the following implementations of the system-dependent
-module:
-
-jmemnobs.c "No backing store": assumes adequate virtual memory exists.
-jmemansi.c Makes temporary files with ANSI-standard routine tmpfile().
-jmemname.c Makes temporary files with program-generated file names.
-jmemdos.c Custom implementation for MS-DOS (16-bit environment only):
- can use extended and expanded memory as well as temp files.
-jmemmac.c Custom implementation for Apple Macintosh.
-
-Exactly one of the system-dependent modules should be configured into an
-installed JPEG library (see install.doc for hints about which one to use).
-On unusual systems you may find it worthwhile to make a special
-system-dependent memory manager.
-
-
-Non-C source code files:
-
-jmemdosa.asm 80x86 assembly code support for jmemdos.c; used only in
- MS-DOS-specific configurations of the JPEG library.
-
-
-CJPEG/DJPEG/JPEGTRAN
-====================
-
-Include files:
-
-cdjpeg.h Declarations shared by cjpeg/djpeg/jpegtran modules.
-cderror.h Additional error and trace message codes for cjpeg et al.
-transupp.h Declarations for jpegtran support routines in transupp.c.
-
-C source code files:
-
-cjpeg.c Main program for cjpeg.
-djpeg.c Main program for djpeg.
-jpegtran.c Main program for jpegtran.
-cdjpeg.c Utility routines used by all three programs.
-rdcolmap.c Code to read a colormap file for djpeg's "-map" switch.
-rdswitch.c Code to process some of cjpeg's more complex switches.
- Also used by jpegtran.
-transupp.c Support code for jpegtran: lossless image manipulations.
-
-Image file reader modules for cjpeg:
-
-rdbmp.c BMP file input.
-rdgif.c GIF file input (now just a stub).
-rdppm.c PPM/PGM file input.
-rdrle.c Utah RLE file input.
-rdtarga.c Targa file input.
-
-Image file writer modules for djpeg:
-
-wrbmp.c BMP file output.
-wrgif.c GIF file output (a mere shadow of its former self).
-wrppm.c PPM/PGM file output.
-wrrle.c Utah RLE file output.
-wrtarga.c Targa file output.
-
-
-RDJPGCOM/WRJPGCOM
-=================
-
-C source code files:
-
-rdjpgcom.c Stand-alone rdjpgcom application.
-wrjpgcom.c Stand-alone wrjpgcom application.
-
-These programs do not depend on the IJG library. They do use
-jconfig.h and jinclude.h, only to improve portability.
-

-INSTALLATION INSTRUCTIONS for the Independent JPEG Group's JPEG software
-
-Copyright (C) 1991-1998, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-This file explains how to configure and install the IJG software. We have
-tried to make this software extremely portable and flexible, so that it can be
-adapted to almost any environment. The downside of this decision is that the
-installation process is complicated. We have provided shortcuts to simplify
-the task on common systems. But in any case, you will need at least a little
-familiarity with C programming and program build procedures for your system.
-
-If you are only using this software as part of a larger program, the larger
-program's installation procedure may take care of configuring the IJG code.
-For example, Ghostscript's installation script will configure the IJG code.
-You don't need to read this file if you just want to compile Ghostscript.
-
-If you are on a Unix machine, you may not need to read this file at all.
-Try doing
- ./configure
- make
- make test
-If that doesn't complain, do
- make install
-(better do "make -n install" first to see if the makefile will put the files
-where you want them). Read further if you run into snags or want to customize
-the code for your system.
-
-
-TABLE OF CONTENTS
------------------
-
-Before you start
-Configuring the software:
- using the automatic "configure" script
- using one of the supplied jconfig and makefile files
- by hand
-Building the software
-Testing the software
-Installing the software
-Optional stuff
-Optimization
-Hints for specific systems
-
-
-BEFORE YOU START
-================
-
-Before installing the software you must unpack the distributed source code.
-Since you are reading this file, you have probably already succeeded in this
-task. However, there is a potential for error if you needed to convert the
-files to the local standard text file format (for example, if you are on
-MS-DOS you may have converted LF end-of-line to CR/LF). You must apply
-such conversion to all the files EXCEPT those whose names begin with "test".
-The test files contain binary data; if you change them in any way then the
-self-test will give bad results.
-
-Please check the last section of this file to see if there are hints for the
-specific machine or compiler you are using.
-
-
-CONFIGURING THE SOFTWARE
-========================
-
-To configure the IJG code for your system, you need to create two files:
- * jconfig.h: contains values for system-dependent #define symbols.
- * Makefile: controls the compilation process.
-(On a non-Unix machine, you may create "project files" or some other
-substitute for a Makefile. jconfig.h is needed in any environment.)
-
-We provide three different ways to generate these files:
- * On a Unix system, you can just run the "configure" script.
- * We provide sample jconfig files and makefiles for popular machines;
- if your machine matches one of the samples, just copy the right sample
- files to jconfig.h and Makefile.
- * If all else fails, read the instructions below and make your own files.
-
-
-Configuring the software using the automatic "configure" script
----------------------------------------------------------------
-
-If you are on a Unix machine, you can just type
- ./configure
-and let the configure script construct appropriate configuration files.
-If you're using "csh" on an old version of System V, you might need to type
- sh configure
-instead to prevent csh from trying to execute configure itself.
-Expect configure to run for a few minutes, particularly on slower machines;
-it works by compiling a series of test programs.
-
-Configure was created with GNU Autoconf and it follows the usual conventions
-for GNU configure scripts. It makes a few assumptions that you may want to
-override. You can do this by providing optional switches to configure:
-
-* If you want to build libjpeg as a shared library, say
- ./configure --enable-shared
-To get both shared and static libraries, say
- ./configure --enable-shared --enable-static
-Note that these switches invoke GNU libtool to take care of system-dependent
-shared library building methods. If things don't work this way, please try
-running configure without either switch; that should build a static library
-without using libtool. If that works, your problem is probably with libtool
-not with the IJG code. libtool is fairly new and doesn't support all flavors
-of Unix yet. (You might be able to find a newer version of libtool than the
-one included with libjpeg; see ftp.gnu.org. Report libtool problems to
-bug-libtool@gnu.org.)
-
-* Configure will use gcc (GNU C compiler) if it's available, otherwise cc.
-To force a particular compiler to be selected, use the CC option, for example
- ./configure CC='cc'
-The same method can be used to include any unusual compiler switches.
-For example, on HP-UX you probably want to say
- ./configure CC='cc -Aa'
-to get HP's compiler to run in ANSI mode.
-
-* The default CFLAGS setting is "-O" for non-gcc compilers, "-O2" for gcc.
-You can override this by saying, for example,
- ./configure CFLAGS='-g'
-if you want to compile with debugging support.
-
-* Configure will set up the makefile so that "make install" will install files
-into /usr/local/bin, /usr/local/man, etc. You can specify an installation
-prefix other than "/usr/local" by giving configure the option "--prefix=PATH".
-
-* If you don't have a lot of swap space, you may need to enable the IJG
-software's internal virtual memory mechanism. To do this, give the option
-"--enable-maxmem=N" where N is the default maxmemory limit in megabytes.
-This is discussed in more detail under "Selecting a memory manager", below.
-You probably don't need to worry about this on reasonably-sized Unix machines,
-unless you plan to process very large images.
-
-Configure has some other features that are useful if you are cross-compiling
-or working in a network of multiple machine types; but if you need those
-features, you probably already know how to use them.
-
-
-Configuring the software using one of the supplied jconfig and makefile files
------------------------------------------------------------------------------
-
-If you have one of these systems, you can just use the provided configuration
-files:
-
-Makefile jconfig file System and/or compiler
-
-makefile.manx jconfig.manx Amiga, Manx Aztec C
-makefile.sas jconfig.sas Amiga, SAS C
-makeproj.mac jconfig.mac Apple Macintosh, Metrowerks CodeWarrior
-mak*jpeg.st jconfig.st Atari ST/STE/TT, Pure C or Turbo C
-makefile.bcc jconfig.bcc MS-DOS or OS/2, Borland C
-makefile.dj jconfig.dj MS-DOS, DJGPP (Delorie's port of GNU C)
-makefile.mc6 jconfig.mc6 MS-DOS, Microsoft C (16-bit only)
-makefile.wat jconfig.wat MS-DOS, OS/2, or Windows NT, Watcom C
-makefile.vc jconfig.vc Windows NT/95, MS Visual C++
-make*.ds jconfig.vc Windows NT/95, MS Developer Studio
-makefile.mms jconfig.vms Digital VMS, with MMS software
-makefile.vms jconfig.vms Digital VMS, without MMS software
-
-Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or
-whatever your system uses as the standard makefile name). For more info see
-the appropriate system-specific hints section near the end of this file.
-
-
-Configuring the software by hand
---------------------------------
-
-First, generate a jconfig.h file. If you are moderately familiar with C,
-the comments in jconfig.doc should be enough information to do this; just
-copy jconfig.doc to jconfig.h and edit it appropriately. Otherwise, you may
-prefer to use the ckconfig.c program. You will need to compile and execute
-ckconfig.c by hand --- we hope you know at least enough to do that.
-ckconfig.c may not compile the first try (in fact, the whole idea is for it
-to fail if anything is going to). If you get compile errors, fix them by
-editing ckconfig.c according to the directions given in ckconfig.c. Once
-you get it to run, it will write a suitable jconfig.h file, and will also
-print out some advice about which makefile to use.
-
-You may also want to look at the canned jconfig files, if there is one for a
-system similar to yours.
-
-Second, select a makefile and copy it to Makefile (or whatever your system
-uses as the standard makefile name). The most generic makefiles we provide
-are
- makefile.ansi: if your C compiler supports function prototypes
- makefile.unix: if not.
-(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES"
-in jconfig.h.) You may want to start from one of the other makefiles if
-there is one for a system similar to yours.
-
-Look over the selected Makefile and adjust options as needed. In particular
-you may want to change the CC and CFLAGS definitions. For instance, if you
-are using GCC, set CC=gcc. If you had to use any compiler switches to get
-ckconfig.c to work, make sure the same switches are in CFLAGS.
-
-If you are on a system that doesn't use makefiles, you'll need to set up
-project files (or whatever you do use) to compile all the source files and
-link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom.
-See the file lists in any of the makefiles to find out which files go into
-each program. Note that the provided makefiles all make a "library" file
-libjpeg first, but you don't have to do that if you don't want to; the file
-lists identify which source files are actually needed for compression,
-decompression, or both. As a last resort, you can make a batch script that
-just compiles everything and links it all together; makefile.vms is an example
-of this (it's for VMS systems that have no make-like utility).
-
-Here are comments about some specific configuration decisions you'll
-need to make:
-
-Command line style
-------------------
-
-These programs can use a Unix-like command line style which supports
-redirection and piping, like this:
- cjpeg inputfile >outputfile
- cjpeg <inputfile >outputfile
- source program | cjpeg >outputfile
-The simpler "two file" command line style is just
- cjpeg inputfile outputfile
-You may prefer the two-file style, particularly if you don't have pipes.
-
-You MUST use two-file style on any system that doesn't cope well with binary
-data fed through stdin/stdout; this is true for some MS-DOS compilers, for
-example. If you're not on a Unix system, it's safest to assume you need
-two-file style. (But if your compiler provides either the Posix-standard
-fdopen() library routine or a Microsoft-compatible setmode() routine, you
-can safely use the Unix command line style, by defining USE_FDOPEN or
-USE_SETMODE respectively.)
-
-To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE".
-
-Selecting a memory manager
---------------------------
-
-The IJG code is capable of working on images that are too big to fit in main
-memory; data is swapped out to temporary files as necessary. However, the
-code to do this is rather system-dependent. We provide five different
-memory managers:
-
-* jmemansi.c This version uses the ANSI-standard library routine tmpfile(),
- which not all non-ANSI systems have. On some systems
- tmpfile() may put the temporary file in a non-optimal
- location; if you don't like what it does, use jmemname.c.
-
-* jmemname.c This version creates named temporary files. For anything
- except a Unix machine, you'll need to configure the
- select_file_name() routine appropriately; see the comments
- near the head of jmemname.c. If you use this version, define
- NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files
- are removed if the program is aborted.
-
-* jmemnobs.c (That stands for No Backing Store :-).) This will compile on
- almost any system, but it assumes you have enough main memory
- or virtual memory to hold the biggest images you work with.
-
-* jmemdos.c This should be used with most 16-bit MS-DOS compilers.
- See the system-specific notes about MS-DOS for more info.
- IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in
- jconfig.h, and include the assembly file jmemdosa.asm in the
- programs. The supplied makefiles and jconfig files for
- 16-bit MS-DOS compilers already do both.
-
-* jmemmac.c Custom version for Apple Macintosh; see the system-specific
- notes for Macintosh for more info.
-
-To use a particular memory manager, change the SYSDEPMEM variable in your
-makefile to equal the corresponding object file name (for example, jmemansi.o
-or jmemansi.obj for jmemansi.c).
-
-If you have plenty of (real or virtual) main memory, just use jmemnobs.c.
-"Plenty" means about ten bytes for every pixel in the largest images
-you plan to process, so a lot of systems don't meet this criterion.
-If yours doesn't, try jmemansi.c first. If that doesn't compile, you'll have
-to use jmemname.c; be sure to adjust select_file_name() for local conditions.
-You may also need to change unlink() to remove() in close_backing_store().
-
-Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM
-setting to a reasonable value for your system (either by adding a #define for
-DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile).
-This value limits the amount of data space the program will attempt to
-allocate. Code and static data space isn't counted, so the actual memory
-needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory
-setting. Larger max-memory settings reduce the amount of I/O needed to
-process a large image, but too large a value can result in "insufficient
-memory" failures. On most Unix machines (and other systems with virtual
-memory), just set DEFAULT_MAX_MEM to several million and forget it. At the
-other end of the spectrum, for MS-DOS machines you probably can't go much
-above 300K to 400K. (On MS-DOS the value refers to conventional memory only.
-Extended/expanded memory is handled separately by jmemdos.c.)
-
-
-BUILDING THE SOFTWARE
-=====================
-
-Now you should be able to compile the software. Just say "make" (or
-whatever's necessary to start the compilation). Have a cup of coffee.
-
-Here are some things that could go wrong:
-
-If your compiler complains about undefined structures, you should be able to
-shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h.
-
-If you have trouble with missing system include files or inclusion of the
-wrong ones, read jinclude.h. This shouldn't happen if you used configure
-or ckconfig.c to set up jconfig.h.
-
-There are a fair number of routines that do not use all of their parameters;
-some compilers will issue warnings about this, which you can ignore. There
-are also a few configuration checks that may give "unreachable code" warnings.
-Any other warning deserves investigation.
-
-If you don't have a getenv() library routine, define NO_GETENV.
-
-Also see the system-specific hints, below.
-
-
-TESTING THE SOFTWARE
-====================
-
-As a quick test of functionality we've included a small sample image in
-several forms:
- testorig.jpg Starting point for the djpeg tests.
- testimg.ppm The output of djpeg testorig.jpg
- testimg.bmp The output of djpeg -bmp -colors 256 testorig.jpg
- testimg.jpg The output of cjpeg testimg.ppm
- testprog.jpg Progressive-mode equivalent of testorig.jpg.
- testimgp.jpg The output of cjpeg -progressive -optimize testimg.ppm
-(The first- and second-generation .jpg files aren't identical since JPEG is
-lossy.) If you can generate duplicates of the testimg* files then you
-probably have working programs.
-
-With most of the makefiles, "make test" will perform the necessary
-comparisons.
-
-If you're using a makefile that doesn't provide the test option, run djpeg
-and cjpeg by hand and compare the output files to testimg* with whatever
-binary file comparison tool you have. The files should be bit-for-bit
-identical.
-
-If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you
-need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t.
-Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h. A less likely
-configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE
-as long should take care of that one.
-
-If the cjpeg test run fails with "Missing Huffman code table entry", it's a
-good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED. Go back to the
-configuration step and run ckconfig.c. (This is a good plan for any other
-test failure, too.)
-
-If you are using Unix (one-file) command line style on a non-Unix system,
-it's a good idea to check that binary I/O through stdin/stdout actually
-works. You should get the same results from "djpeg <testorig.jpg >out.ppm"
-as from "djpeg -outfile out.ppm testorig.jpg". Note that the makefiles all
-use the latter style and therefore do not exercise stdin/stdout! If this
-check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined.
-If it still doesn't work, better use two-file style.
-
-If you chose a memory manager other than jmemnobs.c, you should test that
-temporary-file usage works. Try "djpeg -bmp -colors 256 -max 0 testorig.jpg"
-and make sure its output matches testimg.bmp. If you have any really large
-images handy, try compressing them with -optimize and/or decompressing with
--colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large.
-
-NOTE: this is far from an exhaustive test of the JPEG software; some modules,
-such as 1-pass color quantization, are not exercised at all. It's just a
-quick test to give you some confidence that you haven't missed something
-major.
-
-
-INSTALLING THE SOFTWARE
-=======================
-
-Once you're done with the above steps, you can install the software by
-copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom)
-to wherever you normally install programs. On Unix systems, you'll also want
-to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1)
-in the man-page directory. The pre-fab makefiles don't support this step
-since there's such a wide variety of installation procedures on different
-systems.
-
-If you generated a Makefile with the "configure" script, you can just say
- make install
-to install the programs and their man pages into the standard places.
-(You'll probably need to be root to do this.) We recommend first saying
- make -n install
-to see where configure thought the files should go. You may need to edit
-the Makefile, particularly if your system's conventions for man page
-filenames don't match what configure expects.
-
-If you want to install the IJG library itself, for use in compiling other
-programs besides ours, then you need to put the four include files
- jpeglib.h jerror.h jconfig.h jmorecfg.h
-into your include-file directory, and put the library file libjpeg.a
-(extension may vary depending on system) wherever library files go.
-If you generated a Makefile with "configure", it will do what it thinks
-is the right thing if you say
- make install-lib
-
-
-OPTIONAL STUFF
-==============
-
-Progress monitor:
-
-If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display
-of percent-done progress reports. The routine provided in cdjpeg.c merely
-prints percentages to stderr, but you can customize it to do something
-fancier.
-
-Utah RLE file format support:
-
-We distribute the software with support for RLE image files (Utah Raster
-Toolkit format) disabled, because the RLE support won't compile without the
-Utah library. If you have URT version 3.1 or later, you can enable RLE
-support as follows:
- 1. #define RLE_SUPPORTED in jconfig.h.
- 2. Add a -I option to CFLAGS in the Makefile for the directory
- containing the URT .h files (typically the "include"
- subdirectory of the URT distribution).
- 3. Add -L... -lrle to LDLIBS in the Makefile, where ... specifies
- the directory containing the URT "librle.a" file (typically the
- "lib" subdirectory of the URT distribution).
-
-Support for 12-bit-deep pixel data:
-
-The JPEG standard allows either 8-bit or 12-bit data precision. (For color,
-this means 8 or 12 bits per channel, of course.) If you need to work with
-deeper than 8-bit data, you can compile the IJG code for 12-bit operation.
-To do so:
- 1. In jmorecfg.h, define BITS_IN_JSAMPLE as 12 rather than 8.
- 2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED,
- because the code for those formats doesn't handle 12-bit data and won't
- even compile. (The PPM code does work, as explained below. The GIF
- code works too; it scales 8-bit GIF data to and from 12-bit depth
- automatically.)
- 3. Compile. Don't expect "make test" to pass, since the supplied test
- files are for 8-bit data.
-
-Currently, 12-bit support does not work on 16-bit-int machines.
-
-Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa;
-so you'll want to keep around a regular 8-bit compilation as well.
-(Run-time selection of data depth, to allow a single copy that does both,
-is possible but would probably slow things down considerably; it's very low
-on our to-do list.)
-
-The PPM reader (rdppm.c) can read 12-bit data from either text-format or
-binary-format PPM and PGM files. Binary-format PPM/PGM files which have a
-maxval greater than 255 are assumed to use 2 bytes per sample, LSB first
-(little-endian order). As of early 1995, 2-byte binary format is not
-officially supported by the PBMPLUS library, but it is expected that a
-future release of PBMPLUS will support it. Note that the PPM reader will
-read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming
-data is automatically rescaled to either maxval=255 or maxval=4095 as
-appropriate for the cjpeg bit depth.
-
-The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM
-format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12. Since this
-format is not yet widely supported, you can disable it by compiling wrppm.c
-with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a
-standard 1-byte/sample PPM or PGM file. (Yes, this means still another copy
-of djpeg to keep around. But hopefully you won't need it for very long.
-Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)
-
-Of course, if you are working with 12-bit data, you probably have it stored
-in some other, nonstandard format. In that case you'll probably want to
-write your own I/O modules to read and write your format.
-
-Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in
-order to generate valid Huffman tables. This is necessary because our
-default Huffman tables only cover 8-bit data.
-
-Removing code:
-
-If you need to make a smaller version of the JPEG software, some optional
-functions can be removed at compile time. See the xxx_SUPPORTED #defines in
-jconfig.h and jmorecfg.h. If at all possible, we recommend that you leave in
-decoder support for all valid JPEG files, to ensure that you can read anyone's
-output. Taking out support for image file formats that you don't use is the
-most painless way to make the programs smaller. Another possibility is to
-remove some of the DCT methods: in particular, the "IFAST" method may not be
-enough faster than the others to be worth keeping on your machine. (If you
-do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST
-to a supported method, by adding a #define in jconfig.h.)
-
-
-OPTIMIZATION
-============
-
-Unless you own a Cray, you'll probably be interested in making the JPEG
-software go as fast as possible. This section covers some machine-dependent
-optimizations you may want to try. We suggest that before trying any of
-this, you first get the basic installation to pass the self-test step.
-Repeat the self-test after any optimization to make sure that you haven't
-broken anything.
-
-The integer DCT routines perform a lot of multiplications. These
-multiplications must yield 32-bit results, but none of their input values
-are more than 16 bits wide. On many machines, notably the 680x0 and 80x86
-CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32
-bit multiply. Unfortunately there is no portable way to specify such a
-multiplication in C, but some compilers can generate one when you use the
-right combination of casts. See the MULTIPLYxxx macro definitions in
-jdct.h. If your compiler makes "int" be 32 bits and "short" be 16 bits,
-defining SHORTxSHOR
