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
-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
/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.
