Those with problems using pfuSaveImage on iR - is this within your own app ?
Please could you test with perfly ( hit the 'snap screen' GUI button ).

pfuSaveImage does different things depending if your rendering with Iris or
OpenGL:

#ifdef IRISGL
    lrectread((short)xorg, (short)yorg,
        (short)(xorg+xsize-1), (short)(yorg+ysize-1), scrbuf);
#else /* OPENGL */
    glReadPixels((short)xorg, (short)yorg, (short)xsize, (short)ysize,
         GL_RGBA, GL_UNSIGNED_BYTE, scrbuf);

I saw the note about using scrsave, that uses Iris GL so would do lrectread.

If perfly and perfly_ogl snap screen OK then you have an app problem. If one or
the other doesn't work please let me know.

Cheers
Rob
