This file format was designed to allow multiple PCX files to be stored in one file. This is especially desirable for multi-page faxes (for which the PCX format is often used). Up to 1024 PCX images can be stored in one DCX file.

The DCX construct begins with a simple header, then the PCX files are simply stored end-to-end, complete with their individual headers and palettes. An array in the header called "Pagetable" contains offsets to each PCX. The one piece of vital information not stored with the PCX files under a DCX is their original filenames. See the PCX section of this manual for more about PCX files.
