NAME

       pbmtopsg3 - convert PBM images to Postscript with G3 fax compression

SYNOPSIS

       pbmtopsg3 [--title=title] [--dpi=dpi] [filespec]

DESCRIPTION

       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

OPTIONS

       -title The Postscript title value.  Default is no title.

       -dpi   The resolution of the Postscript output.	Default is 72 dpi.

NAME

       g32pbm - convert a Group 3 fax file into a portable bitmap

SYNOPSIS

       g32pbm [-reversebits] [-stretch] [g3file]

DESCRIPTION

       Reads a Group 3 fax file (raw or digifax) as input. If no filename is given, stdin is used.  Produces a portable bitmap as output.

OPTIONS

       -r     Tells  g32pbm  to  interpret bits least-significant first, instead of the default most-significant first ("-reversebits").  Some fax
	      modems do it one way and others do it the other way. If you get a whole bunch of "invalid code" messages (nearly one per line),  try
	      using this flag.

       -s     Double  each  horizontal row of the fax file in the pbm file ("-stretch)".  You can use this to adjust the aspect ratio of a "normal
	      resolution" fax file to match that of a "fine resolution" fax file.  This might not seem like it belongs here, but it's much  faster
	      than  using pnmscale|pgmtopbm later.  -s is activated automatically if the file is specified on the command line and its name starts
	      with "fn..." (fax/normal).

       -l(aserjet)
	      Instead of a portable bitmap (PBM), output HP laserjet files, suitable for direct printing on a HP laserjet or desjket.

       -d <dpi>
	      Scale output to <dpi> dots per inch before printing. Normal FAX resolution is 204x196 dpi (fine mode), or 204x98 dpi (normal  mode).
	      In LaerJet mode, only the values 75, 150 and 300 are allowed for <dpi>.

       -t     turn image by 90 degrees clockwise. Multiple -t commands increase angle, that is, -t -t will turn it upside down, and so on.

       -?     Print a short command syntax.

REFERENCES

       The standard for Group 3 fax is defined in CCITT Recommendation T.4.

BUGS

       g32pbm  could  be  smarter  about  the  image width, at the moment, the maximum width is 1728 pixels, and the maximum height is 4300 lines.
       Everything bigger is just cut off.

       Only 'raw' pbm files are created.

       Scaling is too slow.

       Turning is too slow (and not yet fully implemented either).
