Memory Usage & PNG Format VS Pixel Format

Hey All,

Memory is determined by cocos2D pixel format not PNG file format

As far as I can tell cocos2D pixel format is the determining factor of how much memory each pixel is going to take. That is if you set it to RGBA8888 all textures loaded from that point on will use RGBA8888 even if they are a PNG-16 on disk.

Can anyone tell me if my assumption is correct? If so it seems rather pointless to do pre-optimization on texture except to possible save some load time ( nominal in most cases ).

Thanks,
Robert

Ok did some research and searched a bit more and dug up that while it has no effect on memory usage leaving the pixel data to the mercy of the repack command isn't very good for quality and should be optimized before hand by the end user for better 16-bit quality.
