Hi Rob!

Thank you for writing. I suppose the only way I'll know for sure is to test this with both.

You could do it this way, although normally for something like this I'd use Core Image. Make two CIImages and use an animated transition CIFilter.

I will take a shot at this. My concern is that I've seen CoreImage transitions bog down initially, I guess in their loading phase or something. I have an early model G5 that I use for testing the low end of the Leopard range (and it still looks strange to say G5 and Low End in the same sentence). On that machine, apps that use CoreImage tend to have a visual stutter initially, and I'm not sure if that's a CI thing or an app specific thing. Is there a 'push' effect for CI though?


That said, CoreImage would theoretically work with Tiger as well, and providing backwards compatibility is something I'm considering anyway. Hmmm. I'll have to test both. Excellent suggestion!

Thank you!
