I'm fairly sure OpenIL can output DXT compressed DDS (DirectDraw
Surface) files. You can then read the DXT compressed data back out
of the DDS file. DXT data is the same format as S3TC, so you can
send it to OpenGL as an S3TC compressed texture.
OpenGL can compress textures on upload, but I don't know if there's
any way to get the raw compressed data back from OpenGL. You
wouldn't want to compress textures every time- it would adversely
affect you level load times.
Thanks for the suggestion, but AFAICT OpenIL doesn't support writing
to compressed formats, only reading them. If anyone knows otherwise,
please let me know...
Cheers,
Jon
