 DC:       I have a requirement to convert Sun colour rasterfiles
 DC: to HPGL
 DC:       format (don't ask why). Does anyone know of a utility to
 DC: do this?
 DC: 
 DC: -- 
 DC: Well, sun is raster, and HPGL is vector. Converting to a true
 DC: vector
 DC: image is a "hard problem." Autocad's CADcamera is often mentioned
 DC: as
 DC: a program that does a good job, using copyrighted/patented techniques.
 DC: (This is from memory, it might be in the weekly posting...)
 DC: 
 DC: If you are NOT going to a REAL vector device, it would be fairly
 DC: easy
 DC: to use rasttopbm (from the pbm toolset) and an awk script to
 DC: create
 DC: a massive file of pen-up pen-downs. PBM is a very simple ascii
 DC: format.
 DC: If you were to send your resulting HPGL file to a plotter, it
 DC: would
 DC: KILL the pen! You probably also need to consider pen width, and
 DC: 
 DC: possibly some unit conversion...

Doug, if you have a .GIF file captured from your SUN Workstation 
you can try a Program like HIJAAK to convert to HPGL.
 
Now that I think about it.. I know we do HPGL to GIF using that program.. 
but haven't gone the other way... I will check at the office today!
