I'm wondering if there are any plans to use Graphics32 in TPicShow. The Graphics32 library is a high-level alternative to Delphi's low-level graphics handling routines, which results in much faster rendering. It would really speed things up. The library is free for commercial and non-commercial use. I'd love to help out, but my programming isn't strong enough right now. The url for Graphics32 is http://www.graphics32.org. Check it out and see if maybe you could use it.
Thanks for the awesome component!
