Re: [PyOpenGL-Users] no blue in texture

[Dave P. <da...@re...>]

I don't have an answer for your color problem, but you ought to consider
using glCopyTexImage2D instead.  It goes straight from the framebuffer
to a texture, without having to read the pixels back first.

e.g.
	glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 0, 0, 128, 128, 0)
