Hello !

Does SDL support BMP transparency?, if YES then how…

Have newer BMP formats some kind of transparency
like GIF format ?

But anyway SDL supports all transparency formats
in that kind that you can blit with ColorKeying.

ColorKeying simply skips pixel that have a certain
color.

See the msdn documentation about bmps if you want to know more.

SDL_image can load transparent BMP files.

AFAIK BMPs do not officially support transparency.

You should use PNGs anyway. BMP is an uncompressed and obsolete format.On 8/29/06, SlntHero at aol.com wrote:
