Denis,

Although it is slightly unintuitive, the function you want is
pfTexture::getImage() (or pfGetTexImage() with the C API). The
declaration looks like this:

pfTexture::getImage(uint **image, int *comp, int *ns,
    int *nt, int *nr);

Where comp is number of components (e.g., 3 for an RGB image), and ns,
nt, nr are the size of the image in x, y, and z directions. If you pass
NULL for any parameter, it will ignore returning that value.

Hope this helps,
Stace
