I would be greatful if someone could provide me with information on the
following Apollo GMR(2-d) package problem:

There is a GMR function called "gm_$print" which allows one to save the
the current information into an external file. I use a system command
"system(prf -trans outputfile)" within my program to print a GMR image
file onto the laser printer.

1. Can I control the output format of my output file so that I can use
   it subsequently in other non-GMR, existing image processing programs?

   For instance, with CVL files, you can after removing the header, process
   the file by treating it as a contiguous sequence of pixels which you
   read in via "getchar" in C.

2. I have grey-level images that need to be printed onto the laser printer,
   but again, it gives only a black/white output.

All help will be appreciated.
