Bit blit (also written BITBLT, BIT BLT, BitBLT, Bit BLT, Bit Blt etc., which stands for bit block transfer) is a data operation commonly used in computer graphics in which several bitmaps are combined into one using a boolean function. The operation involves at least two bitmaps: a "source" (or "foreground") and a … See more The name derives from the BitBLT routine for the Xerox Alto computer, standing for bit-boundary block transfer.

In this example a background image, a sprite, and a 1-bit … See more Blitting is similar to hardware-sprite drawing, in that both systems reproduce a pattern, typically a square area, at different locations on the screen. Hardware sprites have the advantage of being stored in separate memory, and therefore don't disturb the main … See more
