Hi all, Is there an endianess problem with DDS format? I'm using a Core2Duo here and I don't know under which kind of machine the DDS has been tested...
A little explanation: After a bit of investigation (=cleaning stupid copy-paste), I found that the only "true" bug I had was "Changing R, G or B writer's masks doesn't seem to affect reading in 3rd-party readers". Has anybody encountered this before? Writing DDS: It seems the DDS must be BGR in order to make 3rd-party readers work correctly (by inverting R and B channels). Reading DDS: It seems DDS generated (from a JPG) by 3rd party tools are marked RGB but are BGR... Please help and share your experience!
