This is in reference to David Oster's code for saving an image to file:
I've used your image saving code in an existing application. I had to change
a few things to get it to work, such as having gSiz be 16 instead of 8, as I
assume this refers to bit size.(?) I also made the PicHandle global. I
replaced the checkerboard poly draw routine with a copybits routine.
Nothing. So I did a simple drawing instead, which works. From this I deduce
that a copybits routine doesn't get seen by this function and therefore this
leads me to ...
