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.
