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 chel@vangen-

       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 mem-
       ory, fast scaling.
