Re: R: [Plib-devel] texture compression

[<tia...@sa...>]

Hello

If i understand correctly, .DDS are pre-compressed image files. I think 
coding what you are suggesting would be easy, but it would require that 
we decompress the textures ourselves in case the user doesn't have the 
extension (and the final result would have the same compression artifacts).

In FG's case, i think the best option is make it so we can override the 
default Z from FG/SimGear, thus making extension checking our problem 
and allowing the user to choose if he prefers no compression (and so no 
compression artifacts).


Cheers
