defines classes and methods to manage images in your own C++ code. You can use to load/save various file formats, access pixel values, display/transform/filter images, draw primitives (text, faces, curves, 3d objects, ...), compute statistics, manage user interactions on images, and so on... |
 |
defines a single image class able to represent datasets having up to 4-dimensions (from 1d scalar signals to 3d hyperspectral volumetric images), with template pixel types (bool,char,int,float,...). It also handles image collections and sequences. |
 |
isself-contained, thread-safe and highly portable. It fully works on different operating systems (Unix,Windows,MacOS X,*BSD,...) and is compatible with various C++ compilers (Visual C++,g++,clang++,icc,...). |
 |
islightweight. It is made of a single header file CImg.h that must be included in your C++ source. It defines only four different classes, encapsulated in the namespace cimg_library. It can be compiled using a minimal set of standard C++ and system libraries only. No need for exotic or complex dependencies. |
 |
Although not mandatory, can use functionalities of external tools/libraries such as Board, FFMPEG, FFTW3. GraphicsMagick, ImageMagick, Lapack, libcurl, libjpeg, libpng, libtiff, Magick++, OpenEXR OpenCV OpenMPorXMedCon. Moreover, a simple plug-in mechanism allows any user to directly enhance the library capabilities according to his needs. |
 |
is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications. |

Sophia Antipolis.
It was designed to help me and my colleagues developing various image processing algorithms,
for datasets as simple as 2D scalar images, or as complex as 3D volumes of diffusion tensors. I also used it for
courses on image processing I teached at the university. As a result, the Library
has been always intended to be compact, easy to install and to use, multi-platform and generic.
It provides a lot of basic functions that everyone would like to find in a good C++ image processing framework.

group at the 
lab in Caen/France.
I am still using, maintaining and updating the Library, and will probably do it for the next couple of years.
How to Help?
The Library is an open-source C++ library which is mainly developped during
free time. If you enjoy using , you may contribute to the project
in different ways. This will motivate me to continue the work.
●You can help to be more widely known, by displaying a
CImg Flyer at work, in your lab or school
(available in .PDFor.JPEG formats).
●You can report bugs, propose patches or new functionalities, using the
forum.
●You can write
tutorials
or parts of the documentation.
●If you just want to say you've been happy with the library, you can send me a postcard from your place, to the following address :
David Tschumperlé, GREYC (UMR CNRS 6072), Equipe IMAGE, 6 Bd du Maréchal Juin, 14050 Caen Cedex, FRANCE.
