the order listed) before diving into the code.
OVERVIEW
========
This package contains C software to implement JPEG image encoding, decoding,
and transcoding. JPEG (pronounced "jay-peg") is a standardized compression
method for full-color and gray-scale images.
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.
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.
LEGAL ISSUES
============
In plain English:
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,
its user, assume the entire risk as to its quality and accuracy.
This software is copyright (C) 1991-2012, Thomas G. Lane, Guido Vollbeding.
All Rights Reserved except as specified below.
Permission is hereby granted to use, copy, modify, and distribute this
software (or portions thereof) for any purpose, without fee, subject to these
conditions:
(1) If any part of the source code for this software is distributed, then this
README file must be included, with this copyright and no-warranty notice
unaltered; and any additions, deletions, or changes to the original files
must be clearly indicated in accompanying documentation.
(2) If only executable code is distributed, then the accompanying
documentation must state that "this software is based in part on the work of
the Independent JPEG Group".
(3) Permission for use of this software is granted only if the user accepts
full responsibility for any undesirable consequences; the authors accept
NO LIABILITY for damages of any kind.
These conditions apply to any software derived from or based on the IJG code,
not just to the unmodified library. If you use our work, you ought to
acknowledge us.
Permission is NOT granted for the use of any IJG author's name or company name
in advertising or publicity relating to this software or products derived from
it. This software may be referred to only as "the Independent JPEG Group's
software".
We specifically permit and encourage the use of this software as the basis of
commercial products, provided that all warranty or liability claims are
assumed by the product vendor.
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,
ltmain.sh). Another support script, install-sh, is copyright by X Consortium
but is also freely distributable.
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 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 http://www.ijg.org/files/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 currently available 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).
Although this is by far the most detailed and comprehensive exposition of
JPEG publicly available, we point out that it is still missing an explanation
of the most essential properties and algorithms of the underlying DCT
technology.
If you think that you know about DCT-based JPEG after reading this book,
then you are in delusion. The real fundamentals and corresponding potential
of DCT-based JPEG are not publicly known so far, and that is the reason for
all the mistaken developments taking place in the image coding domain.
The original JPEG 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.
IJG JPEG 8 introduces an implementation of the JPEG SmartScale extension
which is specified in two documents: A contributed document at ITU and ISO
with title "ITU-T JPEG-Plus Proposal for Extending ITU-T T.81 for Advanced
Image Coding", April 2006, Geneva, Switzerland. The latest version of this
document is Revision 3. And a contributed document ISO/IEC JTC1/SC29/WG1 N
5799 with title "Evolution of JPEG", June/July 2011, Berlin, Germany.
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. JFIF 1.02 has been adopted as an Ecma International Technical Report
and thus received a formal publication status. It is available as a free
download in PDF format from
http://www.ecma-international.org/publications/techreports/E-TR-098.htm.
A PostScript version of the JFIF document is available at
http://www.ijg.org/files/jfif.ps.gz. There is also a plain text version at
http://www.ijg.org/files/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
http://www.ijg.org/files/. 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.

ACKNOWLEDGMENTS
===============
Thank to Juergen Bruder for providing me with a copy of the common DCT
algorithm article, only to find out that I had come to the same result
in a more direct and comprehensible way with a more generative approach.
Thank to Istvan Sebestyen and Joan L. Mitchell for inviting me to the
ITU JPEG (Study Group 16) meeting in Geneva, Switzerland.
Thank to Thomas Wiegand and Gary Sullivan for inviting me to the
Joint Video Team (MPEG & ITU) meeting in Geneva, Switzerland.
Thank to Thomas Richter and Daniel Lee for inviting me to the
ISO/IEC JTC1/SC29/WG1 (also known as JPEG, together with ITU-T SG16)
meeting in Berlin, Germany.
Thank to John Korejwa and Massimo Ballerini for inviting me to
fruitful consultations in Boston, MA and Milan, Italy.
Thank to Hendrik Elstner, Roland Fassauer, Simone Zuck, Guenther
Maier-Gerber, Walter Stoeber, Fred Schmitz, and Norbert Braunagel
for corresponding business development.
Thank to Nico Zschach and Dirk Stelling of the technical support team
at the Digital Images company in Halle for providing me with extra
equipment for configuration tests.
Thank to Richard F. Lyon (then of Foveon Inc.) for fruitful
communication about JPEG configuration in Sigma Photo Pro software.
Thank to Andrew Finkenstadt for hosting the ijg.org site.
Last but not least special thank to Thomas G. Lane for the original
design and development of this singular software package.
FILE FORMAT WARS
================
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!
TO DO
=====
Version 8 is the first release of a new generation JPEG standard
to overcome the limitations of the original JPEG specification.
More features are being prepared for coming releases...
Please send bug reports, offers of help, etc. to jpeg-info@jpegclub.org.

/*
* A forward DCT routine is given a pointer to an input sample array and
* a pointer to a work area of type DCTELEM[]; the DCT is to be performed
* in-place in that buffer. Type DCTELEM is int for 8-bit samples, INT32
* for 12-bit samples. (NOTE: Floating-point DCT implementations use an
* array of type FAST_FLOAT, instead.)
* The input data is to be fetched from the sample array starting at a
* specified column. (Any row offset needed will be applied to the array
* pointer before it is passed to the FDCT code.)
* Note that the number of samples fetched by the FDCT routine is
* DCT_h_scaled_size * DCT_v_scaled_size.
* The DCT outputs are returned scaled up by a factor of 8; they therefore
* have a range of +-8K for 8-bit data, +-128K for 12-bit data. This
* convention improves accuracy in integer implementations and saves some
* work in floating-point ones.
* Quantization of the output coefficients is done by jcdctmgr.c.

/*
* Although rotating and flipping data expressed as DCT coefficients is not
* hard, there is an asymmetry in the JPEG format specification for images
* whose dimensions aren't multiples of the iMCU size. The right and bottom
* image edges are padded out to the next iMCU boundary with junk data; but
* no padding is possible at the top and left edges. If we were to flip
* the whole image including the pad data, then pad garbage would become
* visible at the top and/or left, and real pixels would disappear into the
* pad margins --- perhaps permanently, since encoders & decoders may not
* bother to preserve DCT blocks that appear to be completely outside the
* nominal image area. So, we have to exclude any partial iMCUs from the
* basic transformation.
*
* Transpose is the only transformation that can handle partial iMCUs at the
* right and bottom edges completely cleanly. flip_h can flip partial iMCUs
* at the bottom, but leaves any partial iMCUs at the right edge untouched.
* Similarly flip_v leaves any partial iMCUs at the bottom edge untouched.
* The other transforms are defined as combinations of these basic transforms
* and process edge blocks in a way that preserves the equivalence.
*
* The "trim" option causes untransformable partial iMCUs to be dropped;
* this is not strictly lossless, but it usually gives the best-looking
* result for odd-size images. Note that when this option is active,
* the expected mathematical equivalences between the transforms may not hold.
* (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim
* followed by -rot 180 -trim trims both edges.)
*
* We also offer a lossless-crop option, which discards data outside a given
* image region but losslessly preserves what is inside. Like the rotate and
* flip transforms, lossless crop is restricted by the JPEG format: the upper
* left corner of the selected region must fall on an iMCU boundary. If this
* does not hold for the given crop parameters, we silently move the upper left
* corner up and/or left to make it so, simultaneously increasing the region
* dimensions to keep the lower right crop corner unchanged. (Thus, the
* output image covers at least the requested region, but may cover more.)
* The adjustment of the region dimensions may be optionally disabled.
*
* We also provide a lossless-resize option, which is kind of a lossless-crop
* operation in the DCT coefficient block domain - it discards higher-order
* coefficients and losslessly preserves lower-order coefficients of a
* sub-block.
*
* Rotate/flip transform, resize, and crop can be requested together in a
* single invocation. The crop is applied last --- that is, the crop region
* is specified in terms of the destination image after transform/resize.
*
* We also offer a "force to grayscale" option, which simply discards the
* chrominance channels of a YCbCr image. This is lossless in the sense that
* the luminance channel is preserved exactly. It's not the same kind of
* thing as the rotate/flip transformations, but it's convenient to handle it
* as part of this package, mainly because the transformation routines have to
* be aware of the option to know how many components to work on.

* IMPORTANT:
* If you are not an expert in concurrent lockless programming, you should
* only be using the atomic lock and reference counting functions in this
* file. In all other cases you should be protecting your data structures
* with full mutexes.
*
* The list of "safe" functions to use are:
* SDL_AtomicLock()
* SDL_AtomicUnlock()
* SDL_AtomicIncRef()
* SDL_AtomicDecRef()
*
* Seriously, here be dragons!
* ^^^^^^^^^^^^^^^^^^^^^^^^^^^
*
* You can find out a little more about lockless programming and the
* subtle issues that can arise here:
* http://msdn.microsoft.com/en-us/library/ee418650%28v=vs.85%29.aspx
*
* There's also lots of good information here:
* http://www.1024cores.net/home/lock-free-algorithms
* http://preshing.com/
*
* These operations may or may not actually be implemented using
* processor specific atomic operations. When possible they are
* implemented as true processor specific atomic operations. When that
* is not possible the are implemented using locks that *do* use the
* available atomic operations.

* and cannot fill the audio buffer in time. A stereo sample consists of
* both right and left channels in LR ordering.

/** \brief Allows back-button-press events on Windows Phone to be marked as handled
*
* Windows Phone devices typically feature a Back button. When pressed,
* the OS will emit back-button-press events, which apps are expected to
* handle in an appropriate manner. If apps do not explicitly mark these
* events as 'Handled', then the OS will invoke its default behavior for
* unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
* terminate the app (and attempt to switch to the previous app, or to the
* device's home screen).
*
* Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
* to mark back-button-press events as Handled, if and when one is sent to
* the app.
*
* Internally, Windows Phone sends back button events as parameters to
* special back-button-press callback functions. Apps that need to respond
* to back-button-press events are expected to register one or more
* callback functions for such, shortly after being launched (during the
* app's initialization phase). After the back button is pressed, the OS
* will invoke these callbacks. If the app's callback(s) do not explicitly
* mark the event as handled by the time they return, or if the app never
* registers one of these callback, the OS will consider the event
* un-handled, and it will apply its default back button behavior (terminate
* the app).
*
* SDL registers its own back-button-press callback with the Windows Phone
* OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
* and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
* it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
* If the hint's value is set to "1", the back button event's Handled
* property will get set to 'true'. If the hint's value is set to something
* else, or if it is unset, SDL will leave the event's Handled property
* alone. (By default, the OS sets this property to 'false', to note.)
*
* SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
* back button is pressed, or can set it in direct-response to a back button
* being pressed.
*
* In order to get notified when a back button is pressed, SDL apps should
* register a callback function with SDL_AddEventWatch(), and have it listen
* for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
* (Alternatively, SDL_KEYUP events can be listened-for. Listening for
* either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
* set by such a callback, will be applied to the OS' current
* back-button-press event.
*
* More details on back button behavior in Windows Phone apps can be found
* at the following page, on Microsoft's developer site:
* http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx
