While we're on the subject of framebuffers, one area which needs to be looked into is the pixel layout for all of:
- little endian byte, little endian pixel 1bpp: word 0 bit 31..0 = pixel 31..0) 16bpp: word 0 bit 31..0 = pixel1 bits 15..0 pixel0 bits 15..0) - little endian byte, big endian pixel 1bpp: word 0 bit 31..0 = pixel 24..31, 16..23, 8..15, 0..7) 16bpp: word 0 bit 31..0 = pixel1 bits 15..0 pixel0 bits 15..0) - big endian byte, big endian pixel 1bpp: word 0 bit 31..0 = pixel 0..31) 16bpp: word 0 bit 31..0 = pixel0 bits 15..0 pixel1 bits 15..0)
We currently do not support all these combinations, and so far I haven't looked into it. It is on my (great long) to do list.
