!Hello. I'm very new to postscript. I've been trying to get a 512x512 pixel
!bitmap to print on our LaserWriter IINT. For some reason or another, I can
!only get 256x256 images to print. When I do a 512x512 all I manage to get
!is a blank page. I tried a 256x512 once and got a few pixels on either side
!of the page, but the center of the image was blank. I've tried this with
!8 bit per sample (the way I get the data from another machine) and 4 bits
!per sample. I'm currently trying to scale it down to 1 bit per sample in
!hopes that this will help.

Most likely your problem is that of limited virtual memory.  When the
image is read in, it is stored (before the image operator can "operate")
- and you may run out of memory before the entire image can be read in.

Solution - simply break up the image into smaller images and use
multiple "image" operators.

Hope that helps.
