pbmtopsg3 - convert PBM images to Postscript with G3 fax compression
pbmtopsg3 [--title=title] [--dpi=dpi] [filespec]
Converts the PBM images in the input PBM file to pages in a Postscript file encoded with G3 fax compression. If you don't specify filespec, the input is from Standard Input. Remember that you can create a multi-image PBM file simply by concatenating single-image PBM files, so if each page is in a different file, you might do: cat faxpage* | pbmtopsg3 >fax.ps
-title The Postscript title value. Default is no title. -dpi The resolution of the Postscript output. Default is 72 dpi.
