Ben, probably a good way to do this without writing much code is to
write a hardware-only plug-in. Upon initialization, when you need the
bitmap, you can write your own code to read back the texture into RAM.
As a shortcut, you might use Core Image to draw it into a bitmap.

Hey all,
I have an FxPlug in which I need to read the frame as a bitmap, do
some pixel analysis, and then apply the results via GPU processing.
The bitmap analysis only needs to happen once, on initialization of
the plug-in...
What's the easiest and best way to do this within an FxPlug?
Thanks,
