Distinguish between bitBlt and pixBlt?
Raster functions that manipulate rectangular pixel arrays are usually referred to as raster ops. Moving a block of pixels from one location to another is also known as a block transfer of pixel values. On a bilevel system, this operation is known as a bitBlt (bit-block transfer), on multilevel system t is known as pixBlt.
