So anyway, I have a game where the tiles are 16x16 but they're being drawn at 32x32. They're real chunky, obviously, so I'd like to come up with a technique for drawing them smoother. I know a lot of video game emulators have a pixel smoothing technique where it looks like they're basically making the pixels more rounded, but I'm wondering if anyone has any sort of ideas on the exact science of it? I'm not looking for a blur effect. I don't have a problem writing a program that can modify images to change pixels, and if no one knows I guess I'll just have to experiment with it until I have something that works....or maybe DeBabelizer or a program like it does the trick.
