I´m goofing around with BitBlt right now and wondering how to get max optimization out of it.
Right now I erase the "source"-pic with .cls, but is this really the fastest way? Would it be better to blit an empty square over the old source-pic instead?
Is there any use in refreashing the source?

This is the (basic) way I figured out:
.cls source - draw source-pic - blit to dest-pic - refresh dest-pic - and back from the beginning.
Iv'e seen lots of versions...what do u think?

Someone said you could store bitmaps in an array for faster transfers with BitBlt, what does that mean?

Hope you can give me a hint, I´m quite a newbie to this.

Cheers
