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.

The basic code that I'm using is

%!PS-Adobe-1.0
100 400 translate
200 200 scale

512 512 4 [512 0 0 -512 0 512]
{<
...OODLES of hex bytes go here...
>} image
showpage

I've had to print out several 256x256 pages and cut and paste (literally).
The little knowledge I have is from the 2 postscript manuals from adobe
(the "red book" and the "blue book"). As I'm not trying to learn all
about postscript I haven't read them cover to cover. I just need to make 
this one project work.

Can anyone out there help me? E-mail me if you can.

Thanx!
