Thanks for the tip! I also noticed that I have to use kCGImageAlphaPremultipliedFirst instead of kCGImageAlphaPremultipliedLast. So, just to summarize for the other people following this discussion, it seem there are two things that have to be in place for sub-pixel font smoothing to work in a CGBitmapContext: - You need to create the context with (kCGImageAlphaPremultipliedFirst | kCGBitmapByteOrder32Host). - Also you must fill the context with a non-transparent background so that the sub-pixel blending can take place. Also, I discovered the GL_BGRA_ext extension can be used to turn such a bitmap into an OpenGL texture.
