Convert \*(tf for facsimile transmission by \*(fx
/var/spool/hylafax/bin/tiff2fax [ options ] file
bin/tiff2fax takes \*(Tf input and generates a \*(Tf Class F image file suitable for facsimile transmission. It is usually invoked by the \*(Fx scheduler process, faxq(8). The default implementation uses the tiffcheck(8) program and tools from the freely available \*(Tf 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 \*(Ps.
/usr/sbin/tiffcheck \*(Tf file conversion examiner /var/spool/hylafax/bin/ps2fax \*(Ps \s-1RIP\s+1 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.
