= B =
bitblt /bit'blit/ n.
[from BLT, q.v.]
1. [common] Any of a family of closely related algorithms for
moving and copying rectangles of bits between main and display
memory on a bit-mapped device, or between two areas of either main
or display memory (the requirement to do the Right Thing in
the case of overlapping source and destination rectangles is what
makes BitBlt tricky). 2. Synonym for blit or BLT. Both
uses are borderline techspeak.
