1. graphapp (Irv M)
Using the graphapp lib, how do I copy a chunk of memory (a virtual screen)
to a window ?
I'm looking for something like Windows' StretchDIBits() (it doesn't have to
do stretching though).
I noticed that there is a structure used with some graphapp functions called
drawings. What do these structures look like (what are the offsets and
meanings of its members) ?

Hi:
I have attached an htm file from the GraphApp manual that (maybe) answers your
question. It seems that a "bitmap" holds an image in off-screen memory, and
GraphApp can copy the image to the screen very rapidly.
There's also a way to peek and poke into that off-screen memory, using
GraphApp. I haven't experimented with either of these, so I can't be sure
the wrappers in graphapp.e work correctly. If not, let me know,
and I'll try to fix the problem.
Regards,
Irv

Thanks. Just one more thing though, I need to know what the bitmap structure
looks like since I won't be using graphapp functions to create them.
