This archive contains example source code how to use the P96
picture-in-picture/overlay feature some graphics cards offer,
in particular the PicassoIV and the CVision3D support them.

Overlays are screen regions within which a separate memory
region in its own color space is shown. For example, an overlay
could display a YUV video on a 256 color screen. Scaling and
color space conversion is performed in hardware, and hence very
fast.

This archive provies source code for creating a high-color (16bit)
overlay on a P96 screen - all provided sufficient bandwidth is
available, and the screen mode supports overlays. 

You will need a compiler (SAS/C preferably) and the P96 development
archive available from iComp. Sources are prepared to be compiled
with registered parameters, small code/data model, no startup code,
but can be easily modified to other settings.
