This chapter covers the operation of the Amiga's blitter, the high speed
line drawing and block movement component of the system. The discussion is
divided into three parts: blitter basics, blitter area fill mode, and
blitter line draw mode.  Some example blitter operations are listed at the
end of the chapter.

For information concerning the blitter hardware in the Enhanced Chip Set,
see  appendix c .
