Abstract

Many computers have the facility of fast handling of bitmaps by use of a bit block transfer instruction (BITBLT). Several methods are available to make use of the BITBLT instructions to speed up pixel manipulation. The pixels do not have to be part of a display bit map, nor do the pixels have to be one bit wide.
