Is there a reason SDL doesn’t support RLE Compressed BMPs? If not I’m
going to add support for loading RLE Compressed BMPs to SDL_LoadBMP.

No reason, other than RLE compressed BMP files are rare, and there
are better compression methods out there in other file formats.

Hardly anyone creates RLE compressed bitmaps anyway! M$ defined it in the
BMP spec but never bothered to implement it, it seems. Windows
paintbrush, for instance, doesn’t bother to compress its bitmaps. Tons of
programs can’t grok compressed bitmaps too. Paintbrush can’t read them,
and Windows 95 will not accept compressed bitmaps for your wallpaper. I
don’t think even Photoshop 4 can write compressed BMP files (there is no
option for RLE compression when saving to that format). The only programs
I know of that create and read RLE BMP’s correctly are The Gimp and
ImageMagick. Both running under Linux (hah!).On Tue, 24 Aug 1999, Stuart Anderson wrote:

Photoshop 4 and 5 does support RLE Bmp’s, but for the reasons Rafael
mentioned their pretty much useless.
