The problem is line 70: infinate8s: you're accessing ImageData.data
without checking the pixel format or pitch. Change to:
id = picture.image_data
if len(id.format == 3):
id.format = 'RGB'
else:
id.format = 'RGBA'
id.pitch = id.width * len(id.format)
pucPixelBuffer = id.data
This will force pyglet to order the components as RGB[A] (not BGR[A]
or [A]RGB or [A]BGR, all common formats you'll see in the wild).
If you load the texture using pyglet functions this will be taken care
of automatically, and will be faster (pyglet knows about OpenGL
extensions to load e.g. BGR data directly, without needing to mush up
the data first). Look at the pyglet.media source code for hints on
how to use pyglet's texture functions with GL_TEXTURE_RECTANGLE_ARB
(and in return, I'll look at making this more accessible in the next
version).
Cheers
Alex.
