[comp.text] Imagen raster file format?

dr2w+@andrew.cmu.edu (Donald J. Ramsay) (04/06/88)

I am trying to write a troff post-filter for our IBM-3812 pager printer
but am limited by the small variety and size of fonts on the printer.
Since I have a set of Imagen Impress-10 font description files and also
the corresponding raster files I thought I could use these as down-loadable
fonts.

The problem is that I don't know how to interpret the raster files.
Although we have a source licence for our AT&T 3B2/400, there were no
source files supplied. Hence the "di10" postprocessor, which must contain
all the information I need, is of little value to me.

Can someone tell me the format of the raster files for the Imagen printer?
(/usr/local/font/devi10/rasti10/<typeface>.<pointsize> on our machine.)
Of course the "di10" source code would be better yet, but we don't want
to pay much since we don't know if its going to work.
Thanks in advance.
