FILE FORMAT WARS
================
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, interoperable format standards for JPEG files.
The ISO/IEC JTC1/SC29/WG1 standards committee (previously known as JPEG,
together with ITU-T SG16) currently promotes different formats containing
the name "JPEG" which is misleading because these formats are incompatible
with original DCT-based JPEG and are based on faulty technologies.
IJG therefore does not and will not support such momentary mistakes
(see REFERENCES).
There exist also distributions under the name "OpenJPEG" promoting such
kind of formats which is misleading because they don't support original
JPEG images.
We have no sympathy for the promotion of inferior formats. Indeed, one of
the original reasons for developing this free software was to help 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.)
The ISO committee pretends to be "responsible for the popular JPEG" in their
public reports which is not true because they don't respond to actual
requirements for the maintenance of the original JPEG specification.
Furthermore, the ISO committee pretends to "ensure interoperability" with
their standards which is not true because their "standards" support only
application-specific and proprietary use cases and contain mathematically
incorrect code.
There are currently different distributions in circulation containing the
name "libjpeg" which is misleading because they don't have the features and
are incompatible with formats supported by actual IJG libjpeg distributions.
One of those fakes is released by members of the ISO committee and just uses
the name of libjpeg for misdirection of people, similar to the abuse of the
name JPEG as described above, while having nothing in common with actual IJG
libjpeg distributions and containing mathematically incorrect code.
The other one claims to be a "derivative" or "fork" of the original libjpeg,
but violates the license conditions as described under LEGAL ISSUES above
and violates basic C programming properties.
We have no sympathy for the release of misleading, incorrect and illegal
distributions derived from obsolete code bases.
Don't use an obsolete code base!
According to the UCC (Uniform Commercial Code) law, IJG has the lawful and
legal right to foreclose on certain standardization bodies and other
institutions or corporations that knowingly perform substantial and
systematic deceptive acts and practices, fraud, theft, and damaging of the
value of the people of this planet without their knowing, willing and
intentional consent.
The titles, ownership, and rights of these institutions and all their assets
are now duly secured and held in trust for the free people of this planet.
People of the planet, on every country, may have a financial interest in
the assets of these former principals, agents, and beneficiaries of the
foreclosed institutions and corporations.
IJG asserts what is: that each man, woman, and child has unalienable value
and rights granted and deposited in them by the Creator and not any one of
the people is subordinate to any artificial principality, corporate fiction
or the special interest of another without their appropriate knowing,
willing and intentional consent made by contract or accommodation agreement.
IJG expresses that which already was.
The people have already determined and demanded that public administration
entities, national governments, and their supporting judicial systems must
be fully transparent, accountable, and liable.
IJG has secured the value for all concerned free people of the planet.
A partial list of foreclosed institutions and corporations ("Hall of Shame")
is currently prepared and will be published later.
TO DO
=====
Version 8 is the first release of a new generation JPEG standard
to overcome the limitations of the original JPEG specification.
Version 9 is the second release of a new generation JPEG standard
to overcome the limitations of the original JPEG specification,
and is the first true source reference JPEG codec.

.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>.

* ansi2knr recognizes function definitions by seeing a non-keyword
* identifier at the left margin, followed by a left parenthesis, with a

* brace as the first token on the following line (ignoring possible
* intervening comments and/or preprocessor directives), except that a line
* consisting of only
* identifier1(identifier2)
* will not be considered a function definition unless identifier2 is
* the word "void", and a line consisting of
* identifier1(identifier2, <<arbitrary>>)
* will not be considered a function definition.
* ansi2knr 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, comments, and preprocessor directives, except that

/*
* 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 2000-04-12 backs out Eggert's changes because of bugs:
- concatlits didn't declare the type of its bufend argument;
- concatlits didn't recognize when it was inside a comment;
- scanstring could scan backward past the beginning of the string; when
- 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.
lpd 1999-08-17 added code to allow preprocessor directives
wherever comments are allowed
lpd 1999-04-12 added minor fixes from Pavel Roskin
<pavel_roskin@geocities.com> for clean compilation with
gcc -W -Wall
lpd 1999-03-22 added hack to recognize lines consisting of
identifier1(identifier2, xxx) as *not* being procedures
lpd 1999-02-03 made indentation of preprocessor commands consistent
lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
endless loop; quoted strings within an argument list
confused the parser
lpd 1999-01-24 added a check for write errors on the output,
suggested by Jim Meyering <meyering@ascend.com>
lpd 1998-11-09 added further hack to recognize identifier(void)
as being a procedure
lpd 1998-10-23 added hack to recognize lines consisting of
identifier1(identifier2) as *not* being procedures
lpd 1997-12-08 made input_file optional; only closes input and/or
output file if not stdin or stdout respectively; prints
usage message on stderr rather than stdout; adds
--filename switch (changes suggested by
<ceder@lysator.liu.se>)
lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
compilers that don't understand void, as suggested by
Tom Lane
lpd 1996-01-15 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 1995-06-22 removed #ifndefs whose sole purpose was to define
undefined preprocessor symbols as 0; changed all #ifdefs
for configuration symbols to #ifs
lpd 1995-04-05 changed copyright notice to make it clear that
including ansi2knr in a program does not bring the entire
program under the GPL
lpd 1994-12-18 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 1994-10-10 removed CONFIG_BROKETS conditional
lpd 1994-07-16 added some conditionals to help GNU `configure',
suggested by Francois Pinard <pinard@iro.umontreal.ca>;
properly erase prototype args in function parameters,

CHANGE LOG for Independent JPEG Group's JPEG software
Version 9b 17-Jan-2016
-----------------------
Improvements and optimizations in DCT and color calculations.
Normalize range limit array composition and access pattern.
Thank to Sia Furler and Maddie Ziegler for inspiration.
Use merged upsample with scaled DCT sizes larger than 8.
Thank to Taylor Hatala for inspiration.
Check for excessive comment lengths in argument parsing in wrjpgcom.c.
Thank to Julian Cohen for hint.
Add makefile.b32 for use with Borland C++ 32-bit (bcc32).
Thank to Joe Slater for contribution.
Document 'f' specifier for jpegtran -crop specification.
Thank to Michele Martone for suggestion.
Use defined value from header instead of hardwired number in rdswitch.c.
Thank to Robert Sprowson for hint.
Version 9a 19-Jan-2014
-----------------------
Add support for wide gamut color spaces (JFIF version 2).
Improve clarity and accuracy in color conversion modules.
Note: Requires rebuild of test images.
Extend the bit depth support to all values from 8 to 12
(BITS_IN_JSAMPLE configuration option in jmorecfg.h).
jpegtran now supports N bits sample data precision with all N from 8 to 12
in a single instance. Thank to Roland Fassauer for inspiration.
Try to resolve issues with new boolean type definition.
Thank also to v4hn for suggestion.
Enable option to use default Huffman tables for lossless compression
(for hardware solution), and in this case improve lossless RGB compression
with reversible color transform. Thank to Benny Alexandar for hint.
Extend the entropy decoding structure, so that extraneous bytes between
compressed scan data and following marker can be reported correctly.
Thank to Nigel Tao for hint.
Add jpegtran -wipe option and extension for -crop.
Thank to Andrew Senior, David Clunie, and Josef Schmid for suggestion.
Version 9 13-Jan-2013
----------------------
Add cjpeg -rgb1 option to create an RGB JPEG file, and insert
a simple reversible color transform into the processing which
significantly improves the compression.
The recommended command for lossless coding of RGB images is now
cjpeg -rgb1 -block 1 -arithmetic.
As said, this option improves the compression significantly, but
the files are not compatible with JPEG decoders prior to IJG v9
due to the included color transform.
The used color transform and marker signaling is compatible with
other JPEG standards (e.g., JPEG-LS part 2).
Remove the automatic de-ANSI-fication support (Automake 1.12).
Thank also to Nitin A Kamble for suggestion.
Add remark for jpeg_mem_dest() in jdatadst.c.
Thank to Elie-Gregoire Khoury for the hint.
Support files with invalid component identifiers (created
by Adobe PDF). Thank to Robin Watts for the suggestion.
Adapt full buffer case in jcmainct.c for use with scaled DCT.
Thank to Sergii Biloshytskyi for the suggestion.
Add type identifier for declaration of noreturn functions.
Thank to Brett L. Moore for the suggestion.
Correct argument type in format string, avoid compiler warnings.
Thank to Vincent Torri for hint.
Add missing #include directives in configuration checks, avoid
configuration errors. Thank to John Spencer for the hint.
Version 8d 15-Jan-2012
-----------------------
Add cjpeg -rgb option to create RGB JPEG files.
Using this switch suppresses the conversion from RGB
colorspace input to the default YCbCr JPEG colorspace.
This feature allows true lossless JPEG coding of RGB color images.
The recommended command for this purpose is currently
cjpeg -rgb -block 1 -arithmetic.
SmartScale capable decoder (introduced with IJG JPEG 8) required.
Thank to Michael Koch for the initial suggestion.
Add option to disable the region adjustment in the transupp crop code.
Thank to Jeffrey Friedl for the suggestion.
Thank to Richard Jones and Edd Dawson for various minor corrections.
Thank to Akim Demaille for configure.ac cleanup.
Version 8c 16-Jan-2011

switch (see above) for lossless JPEG coding.
.B Caution:
A decoder with inverse color transform support is required for
this feature. Reversible color transform support is not yet
widely implemented, so many decoders will be unable to view
a reversible color transformed JPEG file at all.
.TP
.B \-bgycc
Create big gamut YCC JPEG file.
In this type of encoding the color difference components are quantized
further by a factor of 2 compared to the normal Cb/Cr values, thus creating
space to allow larger color values with higher saturation than the normal
gamut limits to be encoded. In order to compensate for the loss of color
fidelity compared to a normal YCC encoded file, the color quantization
tables can be adjusted accordingly. For example,
.B cjpeg \-bgycc \-quality
80,90 will give similar results as
.B cjpeg \-quality
80.
.B Caution:
For correct decompression a decoder with big gamut YCC support (JFIF
version 2) is required. An old decoder may or may not display a big
gamut YCC encoded JPEG file, depending on JFIF version check and
corresponding warning/error configuration. In case of a granted
decompression the old decoder will display the image with half
saturated colors.

## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)

The JPEG standard allows either 8-bit or 12-bit data precision. (For color,

Currently, 9-bit to 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.)
Run-time selection and conversion of data precision are currently not
supported and may be added later.
Exception: The transcoding part (jpegtran) supports all settings in a
single instance, since it operates on the level of DCT coefficients and
not sample values.

format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12. Since this
format, maxval=MAXJSAMPLE, when compiled with BITS_IN_JSAMPLE>8. 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.
Of course, if you are working with 9-bit to 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.
Note:
The standard Huffman tables are only valid for 8-bit data precision. If
you selected more than 8-bit data precision, cjpeg uses arithmetic coding
by default. The Huffman encoder normally uses entropy optimization to
compute usable tables for higher precision. Otherwise, you'll have to
supply different default Huffman tables.

and experimenting with any optional optimizations such as loop unrolling.
(Unfortunately, far too many compilers have optimizer bugs ... be prepared to
back off if the code fails self-test.) If you do any experimentation along
these lines, please report the optimal settings to jpeg-info@uc.ag so we

Microsoft Windows (all versions), generic comments:
Some Windows system include files define typedef boolean as "unsigned char".
The IJG code also defines typedef boolean, but we make it "int" by default.
The IJG code also defines typedef boolean, but we make it an "enum" by default.
This doesn't affect the IJG programs because we don't import those Windows
include files. But if you use the JPEG library in your own program, and some
of your program's files import one definition of boolean while some import the
other, you can get all sorts of mysterious problems. A good preventive step
is to make the IJG library use "unsigned char" for boolean. To do that,
add something like this to your jconfig.h file:
/* Define "boolean" as unsigned char, not int, per Windows custom */
/* Define "boolean" as unsigned char, not enum, per Windows custom */
#ifndef __RPCNDR_H__ /* don't conflict if rpcndr.h already read */
typedef unsigned char boolean;
#endif
#ifndef FALSE /* in case these macros already exist */
#define FALSE 0 /* values of boolean */
#endif
#ifndef TRUE
#define TRUE 1
#endif
#define HAVE_BOOLEAN /* prevent jmorecfg.h from redefining it */
(This is already in jconfig.vc, by the way.)

* These processes all use a common table prepared by the routine below.
*
* For most steps we can mathematically guarantee that the initial value
* of x is within MAXJSAMPLE+1 of the legal range, so a table running from
* -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient. But for the initial
* limiting step (just after the IDCT), a wildly out-of-range value is
* possible if the input data is corrupt. To avoid any chance of indexing
* of x is within 2*(MAXJSAMPLE+1) of the legal range, so a table running
* from -2*(MAXJSAMPLE+1) to 3*MAXJSAMPLE+2 is sufficient. But for the
* initial limiting step (just after the IDCT), a wildly out-of-range value
* is possible if the input data is corrupt. To avoid any chance of indexing
* off the end of memory and getting a bad-pointer trap, we perform the
* post-IDCT limiting thus:
* x = range_limit[x & MASK];
* x = (sample_range_limit - SUBSET)[(x + CENTER) & MASK];
* where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
* samples. Under normal circumstances this is more than enough range and
* a correct output will be generated; with bogus input data the mask will
* cause wraparound, and we will safely generate a bogus-but-in-range output.
* For the post-IDCT step, we want to convert the data from signed to unsigned
* representation by adding CENTERJSAMPLE at the same time that we limit it.
* So the post-IDCT limiting table ends up looking like this:
* CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
* MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
* 0 (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
* 0,1,...,CENTERJSAMPLE-1
* Negative inputs select values from the upper half of the table after
* masking.
*
* We can save some space by overlapping the start of the post-IDCT table
* with the simpler range limiting table. The post-IDCT table begins at
* sample_range_limit + CENTERJSAMPLE.
* This is accomplished with SUBSET = CENTER - CENTERJSAMPLE.
*
* Note that the table is allocated in near data space on PCs; it's small
* enough and used often enough to justify this.

The JPEG standard itself is "color blind" and doesn't specify any particular
color space. It is customary to convert color data to a luminance/chrominance
color space before compressing, since this permits greater compression. The
existing de-facto JPEG file format standards specify YCbCr or grayscale data
(JFIF), or grayscale, RGB, YCbCr, CMYK, or YCCK (Adobe). For special
applications such as multispectral images, other color spaces can be used,

A number of compile-time options are available by modifying jmorecfg.h.
The JPEG standard provides for both the baseline 8-bit DCT process and
a 12-bit DCT process. The IJG code supports 12-bit lossy JPEG if you define
BITS_IN_JSAMPLE as 12 rather than 8. Note that this causes JSAMPLE to be
larger than a char, so it affects the surrounding application's image data.
The sample applications cjpeg and djpeg can support 12-bit mode only for PPM
and GIF file formats; you must disable the other file formats to compile a
12-bit cjpeg or djpeg. (install.txt has more information about that.)
At present, a 12-bit library can handle *only* 12-bit images, not both
precisions. (If you need to include both 8- and 12-bit libraries in a single
application, you could probably do it by defining NEED_SHORT_EXTERNAL_NAMES
for just one of the copies. You'd have to access the 8-bit and 12-bit copies
from separate application source files. This is untested ... if you try it,
we'd like to hear whether it works!)
The IJG code currently supports 8-bit to 12-bit sample data precision by
defining BITS_IN_JSAMPLE as 8, 9, 10, 11, or 12.
Note that a value larger than 8 causes JSAMPLE to be larger than a char,
so it affects the surrounding application's image data.
The sample applications cjpeg and djpeg can support deeper than 8-bit data
only for PPM and GIF file formats; you must disable the other file formats
to compile a 9-bit to 12-bit cjpeg or djpeg. (install.txt has more
information about that.)
Run-time selection and conversion of data precision are currently not
supported and may be added later.
Exception: The transcoding part (jpegtran) supports all settings in a
single instance, since it operates on the level of DCT coefficients and
not sample values.
(If you need to include an 8-bit library and a 9-bit to 12-bit library for
compression or decompression in a single application, you could probably do
it by defining NEED_SHORT_EXTERNAL_NAMES for just one of the copies. You'd
have to access the 8-bit and the 9-bit to 12-bit copies from separate
application source files. This is untested ... if you try it, we'd like to
hear whether it works!)
Note that a 12-bit library always compresses in Huffman optimization mode,
in order to generate valid Huffman tables. This is necessary because our
default Huffman tables only cover 8-bit data. If you need to output 12-bit
files in one pass, you'll have to supply suitable default Huffman tables.
You may also want to supply your own DCT quantization tables; the existing
quality-scaling code has been developed for 8-bit use, and probably doesn't
generate especially good tables for 12-bit.
Note that the standard Huffman tables are only valid for 8-bit data precision.
If you selected more than 8-bit data precision, cjpeg uses arithmetic coding
by default. The Huffman encoder normally uses entropy optimization to
compute usable tables for higher precision. Otherwise, you'll have to
supply different default Huffman tables. You may also want to supply your
own DCT quantization tables; the existing quality-scaling code has been
developed for 8-bit use, and probably doesn't generate especially good tables
for 9-bit to 12-bit.
The maximum number of components (color channels) in the image is determined
by MAX_COMPONENTS. The JPEG standard allows up to 255 components, but we

-bgycc Create big gamut YCC JPEG file.
In this type of encoding the color difference
components are quantized further by a factor of 2
compared to the normal Cb/Cr values, thus creating
space to allow larger color values with higher
saturation than the normal gamut limits to be encoded.
In order to compensate for the loss of color fidelity
compared to a normal YCC encoded file, the color
quantization tables can be adjusted accordingly.
For example, cjpeg -bgycc -quality 80,90 will give
similar results as cjpeg -quality 80.
CAUTION: For correct decompression a decoder with big
gamut YCC support (JFIF version 2) is required.
An old decoder may or may not display a big gamut YCC
encoded JPEG file, depending on JFIF version check
