Re: [PyOpenGL-Users] OpenGL textures

[altern <al...@gm...>]

thanks andrew, i dont know how i did not find this myself, i was looking in
wxBitmap class for this type of function.
still i dont get the images properly displayed. I can see it has similar
colors as the original but it is heavily pixelated. Is there any 
difference in the format of the image data array itself between wx and 
pygame?
