Description:

The CImg Library is a C++ toolkit providing simple classes and functions to
load, save, process and display images in your own C++ code. It consists
only of a single header file CImg.h that must be included in your program
source. It contains useful image processing algorithms for loading/saving,
resizing/rotating, filtering, object drawing (text, lines, faces,
ellipses, ...), etc.

Images are instanciated by a class able to represent images up to 4-dimension
wide (from 1-D scalar signals to 3-D volumes of vector-valued pixels), with
template pixel types. It depends on a minimal number of libraries: you can
compile it with only standard C libraries. No need for exotic libraries and
complex dependencies.
