Hi all, strange things are happening on my machine:

When using glPixelZoom(2, 2) "darkens" the pixels written in the
output buffer. The solution to solve it is to:
- bind texture with a texture magnify filter set to nearest
- disable the texture (glDisable (GL_TEXTURE_2D))
before the call to glPixelZoom is made.

To me, it looks like a bug to the OpenGL driver. AFAIK, the
glPixelZoom shouldn't be affected in anyway by texturing operations...

I'm running my program on the nvidia linux 180.60 drivers.

Regards, Tom

Yes it is....

See the man page for glDrawPixels, mine says:

"Texture mapping, fog, and all the fragment
 operations are applied before the fragments
 are written to the frame buffer."

Tnx for noticing, wouldn't expect it at all! Doesn't seem to make
sense at first glance.
