Putting a bunch of jpg files on an mm document - too slow

[Blake McBride]

Greetings,

I have a bunch of jpg files I need to put into an mm file.  The way I am
doing it right now is:

1. convert jpg files to ps files using:  convert pic.jpg pic.ps
2. Include the pics in the mm file using:  .PSPIC pic.ps 4in
3. Run groff:   groff -mm file.mm >file.ps
4. Convert the file to a PDF file with:  ps2pdf file.ps file.pdf

It works. The problem is that stem #4 takes a long time.  Sometimes more
than five minutes!

I tried using gs directly but that didn't help.

I also tried:

1.  Convert the jpg file to a pdf file with:  convert file.jpg file.ps
2.  Include the picture with:  .PDFPIC file.pdf 4in
3.  Run groff with:  pdfroff -mm -U file.mm >file.pdf

But line 3 gives me the following error:

GPL Ghostscript 9.55.0: Unrecoverable error, exist code 1
Segmentation fault (core dumped)

I'm sure the jpg and mm files are correct.

Any suggestions on including jpg files into an mm document faster?

Thanks!
