Fastest pixel manipultion method?

This is probably a quick newbie question. I am doing my own pixel manipulation using int[] buffers. So I use a BufferedImage with type RGB (not RGBA). So thats 24 bits per color. If I go to fullscreen, is it better to pick 24-bit color, or 16-bit color? 24-bit matches the BufferedImage but 16-bit is less to copy over.

Thanks!

You might be better suited posting this in the Java2D forum, because BufferedImages start to get complicated. I personally don’t know the answer, but I’m sure you’d get better luck there.

I guess its not a newbie question, I post over there. Thanks.
