       tiff2fax - convert TIFF for facsimile transmission by HylaFAX


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


       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.


       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.


       /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


       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.
