image.h

/* 
 * image.h - Image Data Structures and definitions
 *
 * One day, this file will define a common structure
 * for all image / animation / volume type data structures.
 * This will allow me to design and implement a library of
 * pixel processing routines for pre and post processing of
 * image data in the rendering process.  Good examples will be
 * image map filtering, animated image maps, DCT/IDCT algorithms,
 * scalar volume data, a common set of file format readers and converters.
