Bit block transfer bitblt with rop3 operation
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.
