Hello. I have a question about image quality problems I’m seeing under X11 when
using a 16 bit color depth.
Specifically, images that have a lot of gradients show very distinct color
bands/stipes rather than smooth transitions from color to color. Similarly,
images with lots of shading tend to display with strange artifacts.
I assume it’s because, one way or another, the pixels are getting mapped to
their closest color value in the X11 color map. Since functions such as
SDL_SetPalette are for 8 bit surfaces I’m at a loss for how to improve the
display quality short of going with 24 or 32 which aren’t options for me.
Strangely, this even happens when the images themselves have been dropped
to 8bit and contain only 200 colors. I only tried this when I couldn’t
get the original 24 bit images to work.
I’m really at a loss, I’ve started messing around with X functions such
XAllocColor but I decided I’d rather not break out of SDL until I’ve asked
around a bit.
Any ideas? Could it be some problem with X initialization or other obscure
thanks in advance.
