Alpha blending can be an other can of worm. There is premultiplied alpha for correct interpolation between color values with alpha and then there is the lack of per-channel alpha that would be useful for subpixel antialiasing against a transparent background.
- londons_explore 7y agoSubpixel anti-aliasing I suspect is technology that will go the same way as video interlacing... ie. "It works great, has a positive benefit on the user experience, but adds so much system complexity, limits other operations, and is so hard to implement right, that it fell out of use" Today subpixel anti-aliasing is implemented mostly for text only - we've given up implementing it for 2d/3d graphics.
