1255.1don't know, but curiousWRKSYS::CHALTASSomeone chanted eveningWed Mar 05 1997 11:526
    Hmm -- a PS 3D30 only supports 8-bit pixmaps (I think), which is
    one byte per pixel.  A 128 MB pixmap would be about 11.5k pixels
    square, or about 102 times the area displayable on a 1280x1024
    screen. What application is using such a large pixmap?

    Bonsoir,
    
    The customer has found this limitation by program with the routine
    CREATE_PIXMAP.
    
    Bonne soiree,
    
    Jacques.

    Both the width and the height of the pixmap are limited to 32766
    pixels.  Even below this size, a very large pixmap may not fit in main
    memory.
