TIFF2PS(1) USER COMMANDS TIFF2PS(1)
NAME
tiff2ps - convert a TIFF image to PostScript
SYNOPSIS
tiff2ps [ options ] input.tif
DESCRIPTION
tiff2ps reads a TIFF image and writes PostScript or Encapsu-
lated PostScript (EPS) on the standard output. By default,
tiff2ps writes Encapsulated 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 gen-
erated. 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 direc-
tory 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).
-o Set the initial TIFF directory to the IFD at the speci-
fied file offset. This option is useful for selecting
thumbnail images and the like which are hidden using
the SubIFD tag.

TIFF2PS(1) USER COMMANDS TIFF2PS(1)
-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).
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 gen-
erated 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 color-
map, 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 use PostScript Level II support for printing color
images (only bilevel and greyscale images). Does not handle
tiled images.
