Classes
class	image_portable
	Base class for portable image formats. This class provides an interface for reading and writing portable image formats, such as PGM and PPM. It defines pure virtual methods for reading the number of lines and columns of an image, reading an image into a buffer, and writing an image from a buffer. Derived classes must implement these methods to provide support for a specific image format. More...

Macros
#define	allocation_tableau(nom, type, nombre)
	Allocate a dynamic array of a given type and size.
