# Summary
#---------

  The CImg Library is an open-source C++ toolkit for image processing.
  It consists in a single header file 'CImg.h' providing a minimal set of C++
  classes and methods that can be used in your own sources, to load/save,
  process and display images. Very portable (Unix/X11,Windows, MacOS X, FreeBSD, .. ),
  efficient, easy to use, it's a pleasant library for developping image processing
  algorithms in C++.

# Institution
#-------------

 GREYC Image / CNRS UMR 6072 / FRANCE

 The CImg Library project started in 2000, at the INRIA-Sophia
 Antipolis/France ( http://www-sop.inria.fr/ ), in the ROBOTVIS / ODYSSEE Team.
 Since October 2004, it is maintained and developed in the Image team of
 the GREYC Lab (CNRS, UMR 6072), in Caen/France.

# Licenses
#----------

 The source code of the CImg Library is distributed under
 two distinct licenses :

 - The main library file 'CImg.h' is *dual-licensed* :
   It can be either distributed under the CeCILL-C or CeCILL license.
   (see files 'Licence_CeCILL-C_V1-en.txt' and 'Licence_CeCILL_V2-en.txt').
   Both are Free-Software licenses :

     * CeCILL-C is adapted to the distribution of
       library components, and is close in its terms to the well known GNU LGPL license
       (the 'CImg.h' file can thus be used in closed-source products under certain
       conditions, please read carefully the license file).

     * CeCILL is close to (and even compatible with) the GNU GPL license.

 - Most of the other files are distributed under the CeCiLL license
   (file 'Licence_CeCILL_V2-en.txt'). See each file header to see what license applies.

 These two CeCiLL licenses ( http://www.cecill.info/index.en.html ) have been
 created under the supervision of the three biggest research institutions on
 computer sciences in France :

   - CNRS  ( http://www.cnrs.fr/ )
   - CEA   ( http://www.cea.fr/ )
   - INRIA ( http://www.inria.fr/ )

 You have to RESPECT these licenses. More particularly, please carefully read
 the license terms before using the CImg library in commercial products.

# Package structure :
#--------------------

  The main package directory CImg/ is organized as follows :

  - README.txt                 : This file.
  - Licence_CeCILL-C_V1-en.txt : A copy of the CeCiLL-C license file.
  - Licence_CeCILL_V2-en.txt   : A copy of the CeCiLL license.
  - CImg.h                     : The single header file that constitutes the library itself.
  - examples/                  : A directory containing a lot of example programs performing
                                 various things, using the CImg library.
  - html/                      : A directory containing a copy of the CImg web page in html
                                 format. The reference documentation is generated
              		         automatically with the tool 'doxygen' (http://www.doxygen.org).
  - resources/                 : A directory containing some resources files for compiling
                                 CImg examples or packages with various C++ compilers and OS.
  - plugins/                   : A directory containing CImg plug-ins files that can be used to
                                 add specific extra functionalities to the CImg library.

# Getting started
#-----------------

  If you are new to CImg, you should first try to compile the different examples
  provided in the 'examples/' directory, to see what CImg is capable of
  (as CImg is a template-based library, no prior compilation of the library is mandatory).
  Look at the 'resources/' directory to ease this compilation on different plateforms.

  Then, you can look at the documentation 'html/reference/' to learn more about CImg
  functions and classes. Finally, you can participate to the 'Forum' section
  of the CImg web page and ask for help if needed.

# Current list of available CImg plug-ins
#-----------------------------------------

 --------------------------------------------------------------------------------
  - VTK legacy format ('plugins/vtk.h') (April 2011).

    This plug-in allows to save 3d scenes as VTK files.

    by Haz-Edine Assemlal (http://www.cim.mcgill.ca/~assemlal/)

 --------------------------------------------------------------------------------
  - CImg IPL 2nd edition ('plugins/cimg_ipl.h') (September 2009).

    This plug-in allows the conversion between CImg and IplImage structures
    (used in openCV).

    by Hon-Kwok Fung (oldfung - at - graduate.hku.hk)

    PS : This plug-in seems to correct some problems with the first edition,
    when image pixels have a padding offset. Need to be tested before removing
    the old one !

  --------------------------------------------------------------------------------
  - CImg IPL 1st edition ('plugins/cimgIPL.h') (November 2008).

    This plug-in allows the conversion between CImg and IplImage structures
    (used in openCV).

    by Haibo Zheng (haibo.zheng - at - gmail.com)

  --------------------------------------------------------------------------------
  - Draw gradient ('plugins/draw_gradient.h') (November 2008).

    This plug-in can be used to draw color gradient in images.

    by Jerome Boulanger (http://www.irisa.fr/vista/Equipe/People/Jerome.Boulanger.html),

  --------------------------------------------------------------------------------
  - Add file format ('plugins/add_fileformat.h') (September 2007).

    This plug-in shows how to easily add support for your own file format in
    CImg. This can be interesting, since the additional format will be recognized
    in functions 'CImg<T>::save()' and 'CImg<T>::load()' functions.

  --------------------------------------------------------------------------------
  - JPEG Buffer ('plugins/jpeg_buffer.h') (July 2007).

    This plug-in provides functions to read/write images stored in jpeg format
    directly in memory buffers. Interesting when dealing for instance with
    images coming from webcams and stored in memory.

    by Paolo Prete.

  --------------------------------------------------------------------------------
  - NL Means ('plugins/nlmeans.h') (May 2006).

    Implementation of the Non-Local Means algorithm as described in [1] and [2].
