NAME

       tiff2ps - convert a TIFF image to POSTSCRIPTtm

SYNOPSIS

       tiff2ps [ options ] input.tif ...

DESCRIPTION

       tiff2ps reads TIFF images and writes POSTSCRIPT or Encapsulated POSTSCRIPT (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; overriding 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 number.  (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 single 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 suppresses 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 facsimile:
	      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 com-
       mand.

       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.
       Matters are even worse for 4-, 2-, and 1-bit palette images.

BUGS

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