Info-vaxers:
Recently, someone asked about REGIS and/or SIXEL to HPGL translation.
I asked our local graphics-guru about these, here is his answer:

John,
Regarding REGIS-to-HPGL : Although such a transformation is possible,
it would be VERY messy and a nontrivial task. I know of no existing
packages for this transformation.
Regarding SIXEL-to-HPGL : A truly horrendous conversion. SIXEL is a raster
protocol while HPGL is a vector protocol. Raster to vector transformation
is monstrously inefficient and rarely provides reasonable-looking output.
Again, I know of no such existing package.
Of the two approaces to hardcopy, REGIS-to-HPGL would afford the best
results, but writing such a conversion would be a significant task.
Martin.
