Hi, I'm new to pic/groff and I've been having some problems
producing either gif or jpeg images using them.
Try pic2graph.

Hi, create a file foo.pic containing just one line:

if you put foo.jpg into a web page you can see that there is a load
of blank space below the box.

By the way, another weird little quirk which doesn't seem to be

diagram goes beyond the default width as understood by pic then it
starts scaling the image automatically! It's really baffling when it
first happens - you make

Hi, yes, that seems to work well (once I'd downloaded the groff-1.19.1
version of pic2graph, the one that comes with cygwin is buggy). Just one
thing: it (ie convert) antialiases everything including the solid lines.
If I turn off antialiasing it turns it off for the text too. Any
suggestions?
Hmmm, what I didn't notice was that this time the _bottom_ of the image
wasn't getting cropped! So I gave up on pic2graph and just used this:
groff -p -P-pletter file.pic | convert -trim -density 90 - file.jpg
Cheers,
Dave

Hi Dave,
Ah, using pnmraw instead of pnm makes everything 2-3 times faster!
Yes, the textual netpbm formats are handy but processing of large images
is quicker if the binary file format is used most of the time.
That brings the pnm approach down to only twice the time of my final

This seems to be a bug. Please send me an example file together with
the exact command line.

I've never found a good way to script this. The process I use is to
open the postscript file with gimp, crop and save. It would be very
pleasant to have a way to quickly generate high quality cropped
images from groff. If anyone knows how to do that I'd like to
know too.

That brings the pnm approach down to only twice the time of my final
direct to jpeg approach which I guess I can live with. I know it's nice
and flexi but it still seems overkill passing round these raw bitmaps
from command to
