How do I get an image with a lot of diagonal jaggies in it to scroll without flickering?
I’m a bit confused by your description; I can’t see any ‘flickering’ in Stinkoman, and everything’s buffered in Flash anyway, so I assume you’re concerned about the slight jerkiness that’s inevitable in creating the illusion of movement using bitmap graphics. All you can do is use the highest frame rate that performance will allow (probably around 20fps for most Flash movies, but many machines will still struggle to get near that with large/complex imagery), thereby minimising the number of pixels moved per frame to achieve the same speed. Beyond that you’ll have to apply motion blur to the image to smooth out the jumps, or make the transition shorter and more interesting to mask the defects (steadily moving a large, static image into view invites our vision system to look for imperfections and so often looks iffy).
