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 (also 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.)
Furthermore, 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.
There are currently distributions in circulation containing the name
"libjpeg" which claim to be a "derivative" or "fork" of the original
libjpeg, but don't have the features and are incompatible with formats
supported by actual IJG libjpeg distributions. Furthermore, they
violate the license conditions as described under LEGAL ISSUES above.
We have no sympathy for the release of misleading and illegal
distributions derived from obsolete code bases.
Don't use an obsolete code base!

CHANGE LOG for Independent JPEG Group's JPEG software
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
-----------------------
Add option to compression library and cjpeg (-block N) to use
different DCT block size.
All N from 1 to 16 are possible. Default is 8 (baseline format).
Larger values produce higher compression,
smaller values produce higher quality.
SmartScale capable decoder (introduced with IJG JPEG 8) required.
Version 8b 16-May-2010
-----------------------
Repair problem in new memory source manager with corrupt JPEG data.
Thank to Ted Campbell and Samuel Chun for the report.
Repair problem in Makefile.am test target.
Thank to anonymous user for the report.
Support MinGW installation with automatic configure.
Thank to Volker Grabsch for the suggestion.

1. Copy jconfig.vc to jconfig.h, makejdsw.vc6 to jpeg.dsw,

makejdep.vc6 to jpeg.dep, makejdsp.vc6 to jpeg.dsp,

makewdsp.vc6 to wrjpgcom.dsp. (Note that the renaming is critical!)
2. Click on jpeg.dsw and apps.dsw to load the project workspaces.
1. Open the command prompt, change to the main directory and execute the
command line
NMAKE /f makefile.vc setup-vc6
This will move jconfig.vc to jconfig.h and makefiles to project files.

2. Open the workspace file jpeg.dsw, build the library project.

get a message saying that the project files are being updated.)
3. Build the library project, then the applications project.

Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10):
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
2010 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
1. Open the command prompt, change to the main directory and execute the
command line
NMAKE /f makefile.vc setup-v10
This will move jconfig.vc to jconfig.h and makefiles to project files.
(Note that the renaming is critical!)
2. Open the solution file jpeg.sln, build the library project.
(If you are using Visual Studio more recent than 2010 (v10), you'll
probably get a message saying that the project files are being updated.)
3. Open the solution file apps.sln, build the application projects.
4. To perform the self-test, execute the command line
NMAKE /f makefile.vc test-build
5. Move the application .exe files from `app`\Release to an
appropriate location on your path.
5. To perform the self-test, execute the command line
NMAKE /f makefile.vc test
Note:
There seems to be an optimization bug in the compiler which causes the
self-test to fail with the color quantization option.
We have disabled optimization for the file jquant2.c in the library
project file which causes the self-test to pass properly.

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
a 12-bit DCT process. The IJG code supports 12-bit 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
