Save images with alpha in two planes: - RGB data as ETC1 - Alpha as ETC1 (from a greyscale image) The second plane alpha is located right after the RGB plane. The RGBA data is not premultiplied, so that RGB can be encoded at a better quality in ETC1. This should avoid some blockiness artifacts that we can see in the current ETC2 mode (which supports alpha natively). Eventually ETC2 should also support non premultiplied data for a better encoding quality. This patch implements the saver and the loader. @feature |
