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.

       programs in Jef Poskanzers pbmplus package have been used, but al lot of code has been changed  or  added
       to simplify its use for displaying faxes. Value added: low use of memory, fast scaling.
