NAME

       g3toxwd - converts a Group 3 fax file into a displayable xwd file

SYNOPSIS

       g3toxwd  [-kludge]  [-reversebits] [-scale N] [-aspect N] [-skiprows N]
       [-name xwdname] [g3file]

DESCRIPTION

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

OPTIONS

       -kludge
              Tells g3toxwd to skip the first lines for synchronisation.

       -reversebits
              Tells g3toxwd 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 0.58 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.

       -skiprows N
              N faxrows of the input file will be skipped.

       -name <name>
              The name <name> will be put in the output file for xwd.

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

BUGS

       Long fax files are not handled properly.  Output size  fixed  1000x1350
       pixels    defined   at   compile   time.    Please   report   bugs   to
