More precisely it is an ImageMagick tool, and runs on all Unix/Windows/Mac.

You might also want to try the GRASS PNG Driver or X window dump.
Another approach is ps.map to pstopnm|pnmtopng if you prefer.

Here are some Bash scripts for making PNG hardcopies of a GRASS monitor--
===
d.out.png.xwd:
#!/bin/sh
# WYSIWYG but not double buffered
if [ -z $GISBASE ] ; then
        echo "You have to be in GRASS to use this."
        exit
fi
if [ -z "$1" ] ; then
        echo "USAGE: d.out.png PNGfilename  (.png added automatically)"
        echo "       Make a PNG hardcopy of a GRASS monitor"
        exit
else
        OLD_MON=`d.mon -p | awk '{printf "%s", $4}'`
        GRASS_VER=`g.version | awk '{printf "%s", $1 " " $2}'`
        export GRASS_PNGFILE="$1".png
        echo "Exporting to $GRASS_PNGFILE from [$GRASS_VER- Monitor: $OLD_MON]"
        xwd -name "$GRASS_VER- Monitor: $OLD_MON" | xwdtopnm | pnmtopng > $GRASS_PNGFILE
fi

        sleep 1         # wait for file to finish writing
