glPixelZoom(x_zoom,y_zoom)
allows simple rescaling
-
-
glPixelStore*()
controls pixel packing (storing) modes.
-
-
glPixelTransfer*()
controls operations on
generalized
color components as they
move to or from the framebuffer.
-
-
glPixelMap*()
allows the generalized color components
to be modified by table lookups.
Generalized Color Components:
This is our terminology (non-standard) for
the set of numerical values associated to
each pixel.
