TIFF2FAX(8C)							  TIFF2FAX(8C)

NAME
       tiff2fax	- convert TIFF for facsimile transmission by HylaFAX

SYNOPSIS
       /var/spool/hylafax/bin/tiff2fax [ options ] file

DESCRIPTION
       bin/tiff2fax  takes  TIFF input and generates a TIFF Class F image file
       suitable	for facsimile transmission.  It	is usually invoked by the  Hy-
       laFAX scheduler process,	faxq(8C).  The default implementation uses the
       tiffcheck(8C) program and tools from the	freely available TIFF software
       distribution to implement the conversion	operations.

       This  script can	modify outgoing	facsimile, such	as watermarking, To do
       this create a shell script etc/FaxModify	in the spooling	area that  al-
       ters the	document.

OPTIONS
       The following operations	are recognized:

       -1	 Write Group 3 1D-encoded data to the output file.

       -2	 Write Group 3 2D-encoded data to the output file.

       -3	 Write Group 4 MMR-encoded data	to the output file.

       -m pages	 Set  the  maximum  number  of pages that are permitted	in the
		 output	file.  If more pages are present in the	input document
		 then abort processing.

       -o file	 Write	output	to  the	 specified file	instead	of the default
		 foo.tif filename.

       -w width	 Set the output	page width, in pixels.	By default, pages  are
		 1728 pixels wide.

       -l length Set the output	page length in millimeters.  By	default, pages
		 are 297 millimeters long.

       -r vres	 Set the vertical resolution, in lines/inch, at	which to image
		 the POSTSCRIPT.

FILES
       /usr/local/sbin/tiffcheck	TIFF file conversion examiner
       /var/spool/hylafax/bin/ps2fax	POSTSCRIPT RIP for doing complicated conversions
       /usr/local/bin/tiffcp		for converting compression schemes
       /usr/local/bin/tiff2ps		for colorspace and/or image size conversions

BUGS
       Conversions  that  require re-imaging and resizing may result in	images
       that are	poorly placed on the page.

       There is	no way to control how images are treated  when	they  are  re-
       sized; e.g. the original	aspect ratio is	not always maintained.
