NAME

       g3topbm - convert a Group 3 fax file into a portable bitmap

SYNOPSIS

       g3topbm [-kludge] [-reversebits] [-stretch] [g3file]

DESCRIPTION

       Reads a Group 3 fax file as input.  Produces a portable bitmap as output.

OPTIONS

       -kludge
	      Tells g3topbm to ignore the first few lines of the file; sometimes fax files have some junk at the beginning.

       -reversebits
	      Tells  g3topbm 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 "bad code word" messages, try using this flag.

       -stretch
	      Tells g3topbm to stretch the image vertically by duplicating each row.  This is for the low-quality transmission mode.

       All flags can be abbreviated to their shortest unique prefix.
