pbm2g3(1)		     mgetty+sendfax manual		     pbm2g3(1)

NAME
       pbm2g3 -	convert	portable bitmaps (PBM) into G3 fax files

SYNOPSIS
       pbm2g3 [-r] [-w<pagewidth>] [-h<blanklines>] [-d] [-a] [pbmfile]

DESCRIPTION
       Reads  a	 portable bitmap as input, converting it into a	G3 fax file on
       stdout. That file is suitable for faxing	it with	sendfax(8) or queueing
       it  for	faxing	with faxspool(1) (provided that	it gets	a ``.g3'' suf-
       fix).

       faxspool(1) uses	pbm2g3(1) internally to	convert	various	bitmap formats
       into fax	g3 format.

OPTIONS
       -a     byte-aligns  the	end-of-line  codes,  inserting padding bits as
	      necessary.

       -w <page	width>
	      sets the width of	the resulting G3 page. Default is 1728.	If you
	      want to be able to fax it	with sendfax, don't use	anything else.
	      For other	fax programs, 2048, 2432, 864 and 1216 may be  useful.
	      For other	purposes, use what you like.

	      If you set it to 0, the width of the pbm file will be used.

       -h <blank lines>
	      specifies	 the  number  of  blank	lines pbm2g3 should prepend to
	      each page. Default is 0.

	      To produce identical output as pbmplus' pbm2g3 program (with  my
	      patch!)  does, use ``-h 4''.

       -r     reverse the bit order in the bytes.

       -d     will one day make	pbm2g3 prepend a digifax header	to the page.

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

BUGS
       The -d option isn't implemented yet.

       If a raw	pbm file is converted, and the width of	the g3 file is smaller
       than the	width of the pbm file, the former is rounded up	 to  the  next
       multiple	of 8.

AUTHOR
       pbm2g3 is Copyright (C) 1993 by Gert Doering, <gert@greenie.muc.de>. It
       is similar to the pbmtog3 program in Jef	 Poskanzers  pbmplus  package,
       but it's	a complete re-write. No	code is	copied.
