[PyOpenGL-Users] glReadPixels

[Ian M. <geo...@gm...>]

Hello,

So, I'm using glReadPixels(...) to get data for a screenshot.  I would
really like to be able to get data from any framebuffer.  Currently, though,
I can only get data from the screen framebuffer (or
GL_COLOR_ATTACHMENT0_EXT).  I looked at glReadBuffer.  I'm using PyGame and
PyOpenGL, and glGetString(GL_READ_BUFFER) returns None.
glReadBuffer(GL_BACK) crashes.

What's going on?

Ian
