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
       HylaFAX 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
       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/bin/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.
