sff2g3(1)		     mgetty+sendfax manual		     sff2g3(1)

NAME
       sff2g3 -	convert	CAPI SFF fax files into	G3 fax files

SYNOPSIS
       sff2g3 [-r] [-d]	[-v] input.SFF output.%03d.g3

DESCRIPTION
       Reads a Common ISDN API (CAPI) structured file format (SFF) input file,
       and converts every fax page contained in	it to a	raw G3 fax file.

       The input SFF files typically come from fax  reception  programs	 using
       CAPI  on	 active	ISDN cards (isdn4linux,	AVM or DIVA cards) or similar.
       The output G3 files are in the ``native''  format  that	all  other  G3
       utilites	in the mgetty+sendfax package use.

       If the input file name is ``-'',	sff2g3 will read from stdin.

       The output file name should contain a ``%d'' or ``%03d''	part.  It will
       be replaced with	the current page number.  If there is no  page	number
       field, only the last page in the	SFF file will be saved.

OPTIONS
       -r     reverse  the  bit	order in the bytes of the output G3 file.  The
	      input bit	order is fixed.

       -d     will one day make	sff2g3 prepend a digifax header	to the page.

       -v     verbose mode - show what's going on.  Multiple -v	arguments  in-
	      crease debug output level.

REFERENCES
       The  standard  for  Group 3 fax is defined in CCITT Recommendation T.4.
       The   SFF   file	  format   is	specified   in	  the	 CAPI	 specs
       (http://www.capi.org).

BUGS
       The -d option isn't implemented yet.

       The output file name is not yet robust against format string attacks.
