bitblt

(BIT BLock Transfer) In computer graphics, a hardware feature that moves a rectangular block of bits from main memory into display memory. It speeds the display of moving objects (animation, scrolling) on screen.

A hardware bitblt provides fastest speed, but bitblts are also implemented in software, even in non-graphics systems. For example, text scrolls faster when it is copied as a contiguous block (bitblt) to the next part of the window, rather than processing every character on every line. See stretch blt.

bit block transfer

bitblt - /bit'blit/ [BLT] 1. 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. blit, BLT.
