FORMING A DISPLAY WITH SEVERAL DIFFERENT PLA YFIELDS
The graphics library provides the ability to split the screen into several "ViewPorts",
each with its own colors and resolutions. See the
Amiga ROM Kernel Manual for more
information.
USING AN EXTERNAL VIDEO SOURCE
An optional board that provides
genlock is available for the Amiga. Genlock allows you
to bring in your graphics display from an external video source (such as a VCR, camera,
or laser disk player). When you use genlock, the background color is replaced by the
display from this external video source. For more information, see the instructions fur-
nished with the optional board.
