 CHANGE LOG for Independent JPEG Group's JPEG software
 
 
+Version 9d  12-Jan-2020
+-----------------------
+
+Optimize the optimal Huffman code table generation to produce
+slightly smaller files.  Thank to John Korejwa for suggestion.
+Note: Requires rebuild of testimgp.jpg.
+
+Decoding Huffman: Use default tables if tables are not defined.
+Thank to Simone Azzalin for report (Motion JPEG),
+and to Martin Strunz for hint.
+
+Add sanity check in optimal Huffman code table generation.
+Thank to Adam Farley for suggestion.
+
+rdtarga.c: use read_byte(), with EOF check, instead of getc()
+in read_*_pixel().
+Thank to Chijin Zhou for cjpeg potential vulnerability report.
+
+jmemnobs.c: respect the max_memory_to_use setting in
+jpeg_mem_available() computation.  Thank to Sheng Shu and
+Dongdong She for djpeg potential vulnerability report.
+
+jdarith.c, jdhuff.c: avoid left shift of negative value
+compiler warning in decode_mcu_AC_refine().
+Thank to Indu Bhagat for suggestion.
+
+Add x64 (64-bit) platform support, avoid compiler warnings.
+Thank to Jonathan Potter, Feiyun Wang, and Sheng Shu for suggestion.
+
+Adjust libjpeg version specification for pkg-config file.
+Thank to Chen Chen for suggestion.
+
+Restore GIF read and write support from libjpeg version 6a.
+Thank to Wolfgang Werner (W.W.) Heinz for suggestion.
+
+Improve consistency in raw (downsampled) image data processing mode.
+Thank to Zhongyuan Zhou for hint.
+
+Avoid out of bounds array read (AC derived table pointers)
+in start pass in jdhuff.c.  Thank to Peng Li for report.
+
+Improve code sanity (jdhuff.c).
+Thank to Reza Mirzazade farkhani for reports.
+
+Add jpegtran -drop option; add options to the crop extension and wipe
+to fill the extra area with content from the source image region,
+instead of gray out.

+# OPENJPEG Library and Applications
+
+## What is OpenJPEG ? 
+
+OpenJPEG is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of [JPEG 2000](http://www.jpeg.org/jpeg2000), a still-image compression standard from the Joint Photographic Experts Group ([JPEG](http://www.jpeg.org)).  Since April 2015, it is officially recognized by ISO/IEC and ITU-T as a [JPEG 2000 Reference Software](http://www.itu.int/rec/T-REC-T.804-201504-I!Amd2).
+
+## Who can use the code ?
+[![badge-license]][link-license]
+
+Anyone. As the OpenJPEG code is released under the [BSD 2-clause "Simplified" License][link-license], anyone can use or modify the code, even for commercial applications. The only restriction is to retain the copyright in the sources or in the binaries documentation. Of course, if you modified the code in a way that might be of interest for other users, you are encouraged to share it (through a [github pull request](https://github.com/uclouvain/openjpeg/pulls) or by filling an [issue](https://github.com/uclouvain/openjpeg/issues)) but this is not a requirement.
+
+## How to install and use OpenJPEG ?
+API Documentation needs a major refactoring. Meanwhile, you can check [installation](https://github.com/uclouvain/openjpeg/wiki/Installation) instructions and [codec documentation](https://github.com/uclouvain/openjpeg/wiki/DocJ2KCodec).
+    
+## Current Status
+[![badge-build]][link-build]
+
+[![badge-msvc-build]][link-msvc-build] 
+
+[![badge-coverity]][link-coverity]
+
+## Who are the developers ?
+
+The library is developed and maintained by the Image and Signal Processing Group ([ISPGroup](http://sites.uclouvain.be/ispgroup/)), in the Université catholique de Louvain ([UCL](http://www.uclouvain.be/en-index.html), with the support of the [CNES](https://cnes.fr/), the [CS](http://www.c-s.fr/) company and the [intoPIX](http://www.intopix.com) company. The JPWL module has been developed by the Digital Signal Processing Lab ([DSPLab](http://dsplab.diei.unipg.it/)) of the University of Perugia, Italy ([UNIPG](http://www.unipg.it/)).
+
+## Details on folders hierarchy
+
+* src
+  * lib
+    * openjp2: contains the sources of the openjp2 library (Part 1 & 2)
+    * openjpwl: contains the additional sources if you want to build a JPWL-flavoured library.
+    * openjpip: complete client-server architecture for remote browsing of jpeg 2000 images.
+    * openjp3d: JP3D implementation
+    * openmj2: MJ2 implementation
+  * bin: contains all applications that use the openjpeg library
+    * common: common files to all applications
+    * jp2: a basic codec
+    * mj2: motion jpeg 2000 executables
+    * jpip: OpenJPIP applications (server and dec server)
+      * java: a Java client viewer for JPIP
+    * jp3d: JP3D applications
+      * tcltk: a test tool for JP3D
+    * wx
+      * OPJViewer: gui for displaying j2k files (based on wxWidget)
+* wrapping
+  * java: java jni to use openjpeg in a java program
+* thirdparty: thirdparty libraries used by some applications. These libraries will be built only if there are not found on the system. Note that libopenjpeg itself does not have any dependency.
+* doc: doxygen documentation setup file and man pages
+* tests: configuration files and utilities for the openjpeg test suite. All test images are located in [openjpeg-data](https://github.com/uclouvain/openjpeg-data) repository.
+* cmake: cmake related files
+* scripts: scripts for developers
+
+See [LICENSE][link-license] for license and copyright information.
+
+See [INSTALL](https://github.com/uclouvain/openjpeg/blob/master/INSTALL.md) for installation procedures.
+
+See [NEWS](https://github.com/uclouvain/openjpeg/blob/master/NEWS.md) for user visible changes in successive releases.
+
+## API/ABI
+
+An API/ABI timeline is automatically updated [here][link-api-timeline].
+
+OpenJPEG strives to provide a stable API/ABI for your applications. As such it
+only exposes a limited subset of its functions.  It uses a mechanism of
+exporting/hiding functions. If you are unsure which functions you can use in
+your applications, you should compile OpenJPEG using something similar to gcc:
+`-fvisibility=hidden` compilation flag.
+See also: http://gcc.gnu.org/wiki/Visibility
+
+On windows, MSVC directly supports export/hiding function and as such the only
+API available is the one supported by OpenJPEG.
