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.

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,
+The ISO JPEG standards committee actually promotes different formats like
+JPEG-2000 or JPEG-XR which are incompatible with original DCT-based JPEG
+and which are based on faulty technologies. IJG therefore does not and
+will not support such momentary mistakes (see REFERENCES).
+We have little or no sympathy for the promotion 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!
+force convergence on common, interoperable format standards for JPEG files.
+Don't use an incompatible file format!
+(In any case, our decoder will remain capable of reading existing JPEG
+image files indefinitely.)
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.
+v7 is basically just a necessary interim release, paving the way for a
+major breakthrough in image coding technology with the next v8 package
+which is scheduled for release in the year 2010.
-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.

-How does it work?
-=================
-
-This distribution is organized as add-on to the widespread
-Independent JPEG Group's JPEG software.
-
-Thus, once you managed to install the IJG software distribution
-successfully, there should be no additional problems (portability
-issues etc.) to incorporate this package into the library,
-and usage is straightforward.
-
-Transcode given JPEG files simply with a command like
-
- jpegtran -arithmetic [-progressive] < orig.jpg > arit.jpg
-
-into an arithmetic coded version LOSSLESSLY! Since there are
-practically no applications in existence which can handle such
-files, you can only transform it back with the same tool
-
- jpegtran [-optimize] [-progressive] < arit.jpg > orig2.jpg
-
-to verify correct operation.
-
-Thus, you can easily verify the enhanced compression performance
-of the arithmetic coding version compared to the Huffman (with
-fixed or custom tables) version.
-
-The claim to evaluate was that arithmetic coding gives an average
-5-10% compression improvement against Huffman.
-Early tests with this implementation support this claim, and you
-can perform tests with own material.
-
-Here are some actual results:
-
-% ./jpegtran -optimize < testorig.jpg > testopt.jpg
-% ./jpegtran -arithmetic < testorig.jpg > testarit.jpg
-% ./jpegtran < testarit.jpg > testorig2.jpg
-% ./jpegtran -arithmetic -progressive < testorig.jpg > testaritp.jpg
-% ./jpegtran < testaritp.jpg > testorig3.jpg
-% ./jpegtran -optimize < ../butterfly.jpg > ../buttopt.jpg
-% ./jpegtran -progressive < ../butterfly.jpg > ../buttprog.jpg
-% ./jpegtran -arithmetic < ../butterfly.jpg > ../buttarit.jpg
-% ./jpegtran < ../buttarit.jpg > ../butterfly2.jpg
-% ./jpegtran -arithmetic -progressive < ../butterfly.jpg > ../buttaritp.jpg
-% ./jpegtran < ../buttaritp.jpg > ../butterfly3.jpg
-% ls -l test*.jpg

-%
-
-Note that arithmetic coding requires only a single processing
-pass due to its fully-adaptive nature, and compared to one-pass
-(fixed tables) Huffman the arithmetic coded version consistently
-achieves 10% compression improvement.
-Compared with two-pass (custom tables) Huffman the improvement
-is 5-10%.
-
-Note that I wasn't able yet to cross-check interoperability of
-the produced files with other implementations.
-Thus, I can't be sure that the files are compliant to the spec,
-but I hope so and the tests support it.
-The encoding and decoding processes should be correct anyway,
-however, in the sense that they are complementary to each other
-and thus retain data integrity.
-
-I would appreciate any indications for compliance or interoperability
-with other implementations from somebody.
-Please let me know if you are able to cross-check something.
-
-
-Installation
-============
-
-The installation is a 2-stage procedure:
-
-1. Preparing the IJG package for potential incorporation
- of the arithmetic coding feature.
-
-2. Incorporation of the actual arithmetic coding modules
- and enabling the feature for usage.
-
-The reason for this 2-stage process is the hope to make
-step 1 obsolete in future IJG releases.
-The actual implementation should remain separate IMHO due
-to the different usage conditions.
-
-Step 1:
-
-1.1. Copy all files from the subdirectory 'patchv6b' into
- the IJG software's v6b source directory.
- This includes minor patches to some files and 3 extra
- files which hold place for the actual implementation.
-
-1.2. Update your Makefile/Projectfile for the inclusion of
- the 3 extra files. This will be done automatically
- if you use a configure-generated makefile and type
- './configure' (reconfigure).
-
-1.3. Recompile ('make').
-
-See the file 'PATCHES' in 'patchv6b' for details.
-
-Step 2:
-
-2.1. Replace the 3 placeholder files by the actual implementation
- modules.
-
-2.2. Enable application support of the new features by #defining
- C_ARITH_CODING_SUPPORTED and D_ARITH_CODING_SUPPORTED
- in 'jmorecfg.h'.
-
-2.3. Recompile ('make').
-
-Note that I suggest to add 3 placeholder files to the IJG
-distribution. This would remove the need for system-dependent
-changes (Makefiles) and thus considerably simplify the actual
-installation for systems without a configure-generated makefile.

+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

- 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.

-NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT
-WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD

+ - the check for \ + newline in scanstring was unnecessary.
+
+ 2000-03-05 Paul Eggert <eggert@twinsun.com>
+
+ Add support for concatenated string literals.
+ * ansi2knr.c (concatlits): New decl.
+ (main): Invoke concatlits to concatenate string literals.
+ (scanstring): Handle backslash-newline correctly. Work with
+ character constants. Fix bug when scanning backwards through
+ backslash-quote. Check for unterminated strings.
+ (convert1): Parse character constants, too.
+ (appendline, concatlits): New functions.
+ * ansi2knr.1: Document this.

CHANGE LOG for Independent JPEG Group's JPEG software
+Version 7 27-Jun-2009
+----------------------
+
+New scaled DCTs implemented.
+djpeg now supports scalings N/8 with all N from 1 to 16.
+cjpeg now supports scalings 8/N with all N from 1 to 16.
+Scaled DCTs with size larger than 8 are now also used for resolving the
+common 2x2 chroma subsampling case without additional spatial resampling.
+Separate spatial resampling for those kind of files is now only necessary
+for N>8 scaling cases.
+Furthermore, separate scaled DCT functions are provided for direct resolving
+of the common asymmetric subsampling cases (2x1 and 1x2) without additional
+spatial resampling.
+
+cjpeg -quality option has been extended for support of separate quality
+settings for luminance and chrominance (or in general, for every provided
+quantization table slot).
+New API function jpeg_default_qtables() and q_scale_factor array in library.
+
+Added -nosmooth option to cjpeg, complementary to djpeg.
+New variable "do_fancy_downsampling" in library, complement to fancy
+upsampling. Fancy upsampling now uses direct DCT scaling with sizes
+larger than 8. The old method is not reversible and has been removed.
+
+Support arithmetic entropy encoding and decoding.
+Added files jaricom.c, jcarith.c, jdarith.c.
+
+Straighten the file structure:
+Removed files jidctred.c, jcphuff.c, jchuff.h, jdphuff.c, jdhuff.h.
+
+jpegtran has a new "lossless" cropping feature.
+
+Implement -perfect option in jpegtran, new API function
+jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch)
+
+Better error messages for jpegtran fopen failure.
+(DP 203_jpegtran_errmsg.dpatch)
+
+Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c:
+according to Netpbm, the de facto standard implementation of the PNM formats,
+the most significant byte is first. (DP 203_rdppm.dpatch)
+
+Add -raw option to rdjpgcom not to mangle the output.
+(DP 205_rdjpgcom_raw.dpatch)
+
+Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch)
+
+Add extern "C" to jpeglib.h.
+This avoids the need to put extern "C" { ... } around #include "jpeglib.h"
+in your C++ application. Defining the symbol DONT_USE_EXTERN_C in the
+configuration prevents this. (DP 202_jpeglib.h_c++.dpatch)

The
+.B \-quality
+option has been extended in IJG version 7 for support of separate quality
+settings for luminance and chrominance (or in general, for every provided
+quantization table slot). This feature is useful for high-quality
+applications which cannot accept the damage of color data by coarse
+subsampling settings. You can now easily reduce the color data amount more
+smoothly with finer control without separate subsampling. The resulting file
+is fully compliant with standard JPEG decoders.
+Note that the
+.B \-quality
+ratings refer to the quantization table slots, and that the last value is
+replicated if there are more q-table slots than parameters. The default
+q-table slots are 0 for luminance and 1 for chrominance with default tables as
+given in the JPEG standard. This is compatible with the old behaviour in case
+that only one parameter is given, which is then used for both luminance and
+chrominance (slots 0 and 1). More or custom quantization tables can be set
+with
+.B \-qtables
+and assigned to components with

+
+
+Microsoft Windows, Microsoft Visual C++ 2008 Developer Studio (v9):
+
+We include makefiles that should work as project files in Visual Studio
+2008 or later. There is a library makefile that builds the IJG library
+as a static Win32 library, and application makefiles that build the sample
+applications as Win32 console applications. (Even if you only want the
+library, we recommend building the applications so that you can run the
+self-test.)
+
+To use:
+1. Copy jconfig.vc to jconfig.h, makejsln.vc9 to jpeg.sln,
+ makeasln.vc9 to apps.sln, makejvcp.vc9 to jpeg.vcproj,
+ makecvcp.vc9 to cjpeg.vcproj, makedvcp.vc9 to djpeg.vcproj,
+ maketvcp.vc9 to jpegtran.vcproj, makervcp.vc9 to rdjpgcom.vcproj, and
+ makewvcp.vc9 to wrjpgcom.vcproj. (Note that the renaming is critical!)
+2. Click on jpeg.sln and apps.sln to load the project solutions.
+ (If you are using Visual Studio more recent than 2008 (v9), you'll
+ probably get a message saying that the project files are being
+ updated.)
3. Build the library project, then the applications project.
4. Move the application .exe files from `app`\Release to an
appropriate location on your path.

* The advantage of this method is that no data path contains more than one

+ * We also provide FDCT routines with various input sample block sizes for
+ * direct resolution reduction or enlargement and for direct resolving the
+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 output DCT block.
+ *
+ * For N<8 we fill the remaining block coefficients with zero.
+ * For N>8 we apply a partial N-point FDCT on the input samples, computing
+ * just the lower 8 frequency coefficients and discarding the rest.
+ *
+ * We must scale the output coefficients of the N-point FDCT appropriately
+ * to the standard 8-point FDCT level by 8/N per 1-D pass. This scaling
+ * is folded into the constant multipliers (pass 2) and/or final/initial
+ * shifting.

* The advantage of this method is that no data path contains more than one
* multiplication; this allows a very simple and accurate implementation in
* scaled fixed-point arithmetic, with a minimal number of shifts.
+ *
+ * We also provide IDCT routines with various output sample block sizes for
+ * direct resolution reduction or enlargement and for direct resolving the
+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 input DCT block.
+ *
+ * For N<8 we simply take the corresponding low-frequency coefficients of
+ * the 8x8 input DCT block and apply an NxN point IDCT on the sub-block
+ * to yield the downscaled outputs.
+ * This can be seen as direct low-pass downsampling from the DCT domain
+ * point of view rather than the usual spatial domain point of view,
+ * yielding significant computational savings and results at least
+ * as good as common bilinear (averaging) spatial downsampling.
+ *
+ * For N>8 we apply a partial NxN IDCT on the 8 input coefficients as
+ * lower frequencies and higher frequencies assumed to be zero.
+ * It turns out that the computational effort is similar to the 8x8 IDCT
+ * regarding the output size.
+ * Furthermore, the scaling and descaling is the same for all IDCT sizes.
+ *
+ * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases
+ * since there would be too many additional constants to pre-calculate.

- * This file is part of the Independent JPEG Group's software.

- *
- * This file contains inverse-DCT routines that produce reduced-size output:
- * either 4x4, 2x2, or 1x1 pixels from an 8x8 DCT block.
- *
- * The implementation is based on the Loeffler, Ligtenberg and Moschytz (LL&M)
- * algorithm used in jidctint.c. We simply replace each 8-to-8 1-D IDCT step
- * with an 8-to-4 step that produces the four averages of two adjacent outputs
- * (or an 8-to-2 step producing two averages of four outputs, for 2x2 output).
- * These steps were derived by computing the corresponding values at the end
- * of the normal LL&M code, then simplifying as much as possible.
- *
- * 1x1 is trivial: just take the DC coefficient divided by 8.
- *
- * See jidctint.c for additional comments.

INTRODUCTION
-These programs implement JPEG image compression and decompression. JPEG
-(pronounced "jay-peg") is a standardized compression method for full-color
-and gray-scale images. JPEG is designed to handle "real-world" scenes,
-for example scanned photographs. Cartoons, line drawings, and other
-non-realistic images are not JPEG's strong suit; on that sort of material
-you may get poor image quality and/or little compression.
-
-JPEG is lossy, meaning that the output image is not necessarily identical to
-the input image. Hence you should not use JPEG if you have to have identical
-output bits. However, on typical real-world images, very good compression
-levels can be obtained with no visible change, and amazingly high compression
-is possible if you can tolerate a low-quality image. You can trade off image
-quality against file size by adjusting the compressor's "quality" setting.

+The -quality option has been extended in IJG version 7 for support of separate
+quality settings for luminance and chrominance (or in general, for every
+provided quantization table slot). This feature is useful for high-quality
+applications which cannot accept the damage of color data by coarse
+subsampling settings. You can now easily reduce the color data amount more
+smoothly with finer control without separate subsampling. The resulting file
+is fully compliant with standard JPEG decoders.
+Note that the -quality ratings refer to the quantization table slots, and that
+the last value is replicated if there are more q-table slots than parameters.
+The default q-table slots are 0 for luminance and 1 for chrominance with
+default tables as given in the JPEG standard. This is compatible with the old
+behaviour in case that only one parameter is given, which is then used for
+both luminance and chrominance (slots 0 and 1). More or custom quantization
+tables can be set with -qtables and assigned to components with -qslots

+CAUTION: You must explicitely add -sample 1x1 for efficient separate color
+quality selection, since the default value used by library is 2x2!

The -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
