Abstract / scope

This document specifies a set of compression methods for coding one or more images of bi-level, continuous-tone greyscale, or continuous-tone colour, or multichannel digital samples.

This document:

—     specifies decoding processes for converting compressed image data to reconstructed image data;

—     specifies a codestream syntax containing information for interpreting the compressed image data;

—     provides guidance on encoding processes for converting source image data to compressed image data.
