Unfortunately it's not quite that easy, Upp Image formats are not standard RGBA. Depending on the platform they could be BGRA (Win32) or ARGB (see Core/Color.h). Unfortunately there is no GL unpacking format that copes with this directly, so it requires an Image copy with some byte swapping.

Thank you James,

I tried the above code that simplified the code of the tutorial. But unfortunatly it doesn't work Confused

I got only a beautiful white rotating cube with no track of texture. I tried several things without success. I do not know if the problem reside in the swapping procedure or somewhere else. I attach the code in case somebody has time to check it.

Thanks,
Luigi
