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
       HylaFAX scheduler process, faxq(8).  The default implementation uses the tiffcheck(8) 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
       alters 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/sbin/tiffcheck		TIFF file conversion examiner
       /var/spool/hylafax/bin/ps2fax	POSTSCRIPT RIP for doing complicated conversions
       /usr/bin/tiffcp			for converting compression schemes
       /usr/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 resized; e.g. the original aspect ratio is not always maintained.
