NAME

       g3tolj - converts a Group 3 fax file into a printable HP-PCL file

SYNOPSIS

       g3tolj   [-kludge]   [-reversebits]  [-scale N]  [-aspect N]  [-resolution 75|100|150|300]
       [-compress 0|1|2] [-pagelength N] [-duplength N] [g3file]

DESCRIPTION

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

OPTIONS

       -kludge
              Tells g3tolj to skip the first lines for synchronisation.

       -reversebits
              Tells  g3tolj  to  interpret  bits  least-significant first, instead of the default
              most-significant first.  Apparently some fax modems do it one way and others do  it
              the other way.  If you get a whole bunch of "invalid code" messages, try using this
              flag.

       -scale N
              Scale the output to match the printer resolution and paper  size,  the  default  of
              1.40 will do in most cases.

       -aspect N
              Scale the output to match the printer resolution and paper size, the default of 1.0
              will do for high resolution faxes, 2.0 will do for low resolution faxes.

       -resolution 75|100|150|300
              Selects print resolution. The default is 300.

       -compress 0|1|2
              Selects compression method for the print output. 0 = none, 1 = rll, 2 = tiff.   The
              default is 0.

       -pagelength N
              Defines  the  pagelength  in  inches,  the  default  is  10.95. After this length a
              pagebreak is generated and the last part of the previous page is duplicated on  the
              next page

       -duplength N
              Defines the length in inches that will be duplicated after a pagebreak, The default
              is 0.7.

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