+# Main CMakeLists.txt to build the OpenJPEG project using CMake (www.cmake.org)
+# Written by Mathieu Malaterre
+
+# This CMake project will by default create a library called openjpeg
+# But if you want to use this project within your own (CMake) project
+# you will eventually like to prefix the library to avoid linking confusion
+# For this purpose you can define a CMake var: OPENJPEG_NAMESPACE to whatever you like
+# e.g.:
+# set(OPENJPEG_NAMESPACE "GDCMOPENJPEG")

+# 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.

+@brief Sparse array management
+
+The functions in this file manage sparse arrays. Sparse arrays are arrays with
+potential big dimensions, but with very few samples actually set. Such sparse
+arrays require allocating a low amount of memory, by just allocating memory
+for blocks of the array that are set. The minimum memory allocation unit is a
+a block. There is a trade-off to pick up an appropriate dimension for blocks.
+If it is too big, and pixels set are far from each other, too much memory will
+be used. If blocks are too small, the book-keeping costs of blocks will raise.
