Well... The code in the newsletter is correct, and is indeed very fast at doing what it does -- however, it is poking a bunch of abstract data to the buffer to show how it works.
Very nice, but unless I can figure out how to manipulate *usable* graphic data directly in the buffer, it doesn't really help me.
I've looked at the different suggestions people brought up above, but so far I still have not been able to convert any of it to a working function.
All my attempts so far have resulted inimages with messed up palettes, although there are differences between the various versions... Just haven't nailed it yet.
