I think it should not... If I recall correctly, Qt can handle 32bpp and 8bpp
images, and 8bpp images are expanded on the fly when drawn on the screen.
The drawing may take a bit longer to complete (but maybe not, since there are
fewer bytes to read), but the memory saving, as you say, may be worth the 
penalty.
