9.2.11 Move BitBLT with Color Expansion
S1D13A04
X37A-G-003-05
The Move BitBLT with Color Expansion takes a monochrome bitmap as the source and
color expands it into the destination. All bits set to one in the source are expanded to desti-
nation pixels of the selected foreground color. All bits set to zero in the source are expanded
to pixels of the selected background color.
The Move BitBLT with Color Expansion is used to accelerate text drawing. A monochrome
bitmap of a font, in off-screen video memory, occupies very little space and takes
advantage of the hardware acceleration. Since the foreground and background colors are
programmable, text of any color can be created.
The Move BitBLT with Color Expansion can move data from one rectangular area to
another, or either the source or destination may be specified to be linear. Storing rectangular
display data in linear format in off screen memory results in a tremendous space saving.
