Module Name:
htmapclr.h
Abstract:
This module contains all halftone color mapping constants for the
htmapclr.c
Author:
28-Mar-1992 Sat 20:56:27 updated -by- Daniel Chou (danielc)
Add in ULDECI4 type, to store the stretchfacor (source -> dest)
add StretchFactor in StretchInfo data structure.
Add support for StretchFactor (ULDECI4 format), so we can internally
turn off VGA16 when the bitmap is badly compressed.
