PixelFormat

Reportedly the most common pixel format 16bpp is 5x5x5. There are ways to test whether a given video card supports either 5x5x5 or 5x6x5.

most common 555? where did you get this information from?
i have not seen a up-to-date 555 card so far, all my pcs and those of my friends are 565...
well, of course that is not very representative

Reportedly is just that; I personally don''t think 5x5x5 would be as common as one game programming book I''ve read claims it to be. I don''t claim that it''s correct, rather I would suggest testing the pixel format and avoiding assumptions altogether. If some code is desired I can post a snippet that demonstrates this.

I don''t know any 5-5-5 video card except this ATI-crap!

of course you may not just assume that an user has a gfx card capable of a certain rgb format, but you have to test for it.
i am having quite a lot of trouble with transparency on 555 cards because as i said i don''t know anyone with a 555 card and can''t test out if it works

Which part of the transparency are you having troubles with? the colory keying?

-Cicco

did i say transparency? i meant translucency

well, you know that you have to shift a lot when you combine the pixels in translucency, and the problem is that i think it SHOULD work on RGB555 cards because i am testing for it and acting accordingly, but some guy over the net said it would look all wrong on his card...

My old S3Virge DX 4MB is another example of 5-5-5 video-card.
