For troff.org, where I want the images to be generated from the given
troff source, I use

    groff "$@" |
    gs -q -r144 \
        -sDEVICE=pnmraw -sPAPERSIZE=a4 -sOutputFile=- \
        -dTextAlphaBits=4 -dGraphicsAlphaBits=4 - |
    pnmcrop -quiet |
    pnmmargin -white 10 |
    pnmtopng -quiet -interlace -compression 9

netpbm does the hard work with pnmcrop and pnmmargin.

Cheers,


Ralph.
