Re: [PyOpenGL-Users] glTexImage2d size

[Matt B. <ma...@rt...>]

Oh, cool, I didn't know about that function, might have to check that out. In 
my current game I'm just making them all a power of 2, which works well 
enough for most things (I like having the extra space to work with in the 
image just in case I or someone else chooses to edit the look of things a bit 
later on), but to save disk space/memory I re-sized my player's weapon images 
some to make them a power of 2, and then expand the OpenGL surface out to the 
aspect ratio of the "correct" original gun image....since I'm downsizing the 
image in one dimension, I lose some detail.
