NAME

6       tiff2fax - convert TIFF for facsimile transmission by HylaFAX
7

SYNOPSIS

9       /var/spool/hylafax/bin/tiff2fax [ options ] file
10

DESCRIPTION

12       bin/tiff2fax  takes  TIFF input and generates a TIFF Class F image file
13       suitable for facsimile transmission.  It  is  usually  invoked  by  the
14       HylaFAX  scheduler  process, faxq(8C).  The default implementation uses
15       the tiffcheck(8C) program and tools  from  the  freely  available  TIFF
16       software distribution to implement the conversion operations.
17
18       This  script can modify outgoing facsimile, such as watermarking, To do
19       this create a shell script etc/FaxModify  in  the  spooling  area  that
20       alters the document.
21

OPTIONS

23       The following operations are recognized:
24
25       -1        Write Group 3 1D-encoded data to the output file.
26
27       -2        Write Group 3 2D-encoded data to the output file.
28
29       -3        Write Group 4 MMR-encoded data to the output file.
30
31       -color    Write  color data to an output file (possibly a separate file
32                 if Group 3 or Group 4 data is also being output).
33
34       -i jobid  How the server references the associated Job ID number
35
36       -m pages  Set the maximum number of pages that  are  permitted  in  the
37                 output file.  If more pages are present in the input document
38                 then abort processing.
39
40       -o file   Write output to the specified file  instead  of  the  default
41                 foo.tif filename.
42
43       -w width  Set  the output page width, in pixels.  By default, pages are
44                 1728 pixels wide.
45
46       -l length Set the output page length in millimeters.  By default, pages
47                 are 297 millimeters long.
48
49       -r vres   Set the vertical resolution, in lines/inch, at which to image
50                 the POSTSCRIPT.
51
52       -S        Simple mode.  Serves as a  format  conversion  interface  for
53                 RTFCC in faxsend to utilize /usr/bin/tiffcp.

FILES

56       /usr/sbin/tiffcheck              TIFF file conversion examiner
57       /var/spool/hylafax/bin/ps2fax    POSTSCRIPT RIP for doing complicated conversions
58       /usr/bin/tiffcp                  for converting compression schemes
59       /usr/bin/tiff2ps                 for colorspace and/or image size conversions
60

BUGS

62       Conversions  that  require re-imaging and resizing may result in images
63       that are poorly placed on the page.
64
65       There is no way to  control  how  images  are  treated  when  they  are
66       resized; e.g. the original aspect ratio is not always maintained.
