NAME
       tiff2ps - convert a TIFF image to POSTSCRIPT™

SYNOPSIS
       tiff2ps [ options ] input.tif ...

DESCRIPTION
       tiff2ps	reads  TIFF images and writes POSTSCRIPT or Encapsulated POST‐
       SCRIPT (EPS) on the standard output.  By default, tiff2ps writes Encap‐
       sulated	POSTSCRIPT  for	 the  first  image in the specified TIFF image
       file.

       By default, tiff2ps will generate POSTSCRIPT that fills a printed  area
       specified  by  the  TIFF	 tags in the input file.  If the file does not
       contain XResolution or YResolution tags, then the printed area  is  set
       according  to  the image dimensions.  The -w and -h options (see below)
       can be used to set the dimensions of the printed area in inches;	 over‐
       riding any relevant TIFF tags.

       The  POSTSCRIPT	generated  for	RGB, palette, and CMYK images uses the
       colorimage  operator.   The  POSTSCRIPT	generated  for	greyscale  and
       bilevel	images	uses the image operator.  When the colorimage operator
       is used, POSTSCRIPT code to emulate this operator on  older  POSTSCRIPT
       printers	 is also generated.  Note that this emulation code can be very
       slow.

       Color images with associated alpha data are  composited	over  a	 white
       background.

OPTIONS
       -1     Generate POSTSCRIPT Level I (the default).

       -2     Generate POSTSCRIPT Level II.

       -a     Generate output for all IFDs (pages) in the input file.

       -d     Set  the	initial TIFF directory to the specified directory num‐
	      ber.  (NB: directories are numbered  starting  at	 zero.)	  This
	      option  is useful for selecting individual pages in a multi-page
	      (e.g. facsimile) file.

       -e     Force the generation of Encapsulated POSTSCRIPT.

       -h     Specify the vertical size of the printed area (in inches).

       -i     Enable/disable pixel interpolation.  This option requires a sin‐
	      gle  numeric value: zero to disable pixel interpolation and non-
	      zero to enable.  The default is enabled.

       -m     Where possible render using the  imagemask  POSTSCRIPT  operator
	      instead  of  the	image operator.	 When this option is specified
	      tiff2ps will use imagemask for rendering 1 bit deep images.   If
	      this  option  is	not specified or if the image depth is greater
	      than 1 then the image operator is used.

       -o     Set the initial TIFF directory to the IFD at the specified  file
	      offset.	This  option  is useful for selecting thumbnail images
	      and the like which are hidden using the SubIFD tag.

       -p     Force the generation of (non-Encapsulated) POSTSCRIPT.

       -s     Generate output for a single IFD (page) in the input file.

       -w     Specify the horizontal size of the printed area (in inches).

       -z     When generating POSTSCRIPT Level II, data is scaled so  that  it
	      does  not	 image	into  the deadzone on a page (the outer margin
	      that the printing device is unable to mark).  This  option  sup‐
	      presses  this  behaviour.	 When POSTSCRIPT Level I is generated,
	      data is imaged to the entire printed page and this option has no
	      affect.

EXAMPLES
       The  following generates POSTSCRIPT Level II for all pages of a facsim‐
       ile:
	      tiff2ps -a2 fax.tif | lpr
       Note also that if you have version 2.6.1 or newer of  Ghostscript  then
       you can efficiently preview facsimile generated with the above command.

       To  generate  Encapsulated POSTSCRIPT for a the image at directory 2 of
       an image use:
	      tiff2ps -d 1 foo.tif
       (notice that directories are numbered starting at zero.)

BUGS
       Because POSTSCRIPT does not support the notion  of  a  colormap,	 8-bit
       palette	images	produce	 24-bit	 POSTSCRIPT  images.   This conversion
       results in output that is six times bigger than the original image  and
       which  takes a long time to send to a printer over a serial line.  Mat‐
       ters are even worse for 4-, 2-, and 1-bit palette images.

BUGS
       Does not handle tiled images when generating PS Level I output.
