NAME
tiff2ps - convert a TIFF image to POSTSCRIPT
SYNOPSIS
tiff2ps [ options ] input.tif ...
DESCRIPTION
tiff2ps reads TIFF images 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 1 (the default).
-2 Generate POSTSCRIPT Level 2.
-3 Generate POSTSCRIPT Level 3. It basically allows one to
use the /flateDecode filter for ZIP compressed TIFF
images.
-a Generate output for all IFDs (pages) in the input file.
-b Specify the bottom margin for the output (in inches).
This does not affect the height of the printed image.
-c Center the image in the output. This option only shows
an effect if both the -w and the -h option are given.
-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.

TIFF2PS(1) USER COMMANDS TIFF2PS(1)
-e Force the generation of Encapsulated POSTSCRIPT
(implies -z).
-h Specify the vertical size of the printed area (in
inches).
-H Specify the maximum height of image (in inches). Images
with larger sizes will be splitted in several pages.
Option -L may be used for specifying size of splitted
images overlapping.
-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.
-L Specify the size of overlapping for splitted images (in
inches). Used in conjuction with -H option.
-l Specify the left margin for the output (in inches).
This does not affect the width of the printed image.
-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 speci-
fied 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.
-r Rotate image by 180 degrees.
-s Generate output for a single IFD (page) in the input
file.
-w Specify the horizontal size of the printed area (in
inches).
-x Override resolution units specified in the TIFF as cen-
timeters.
-y Override resolution units specified in the TIFF as
inches.
-z When generating POSTSCRIPT Level 2, 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 1 is generated, data is imaged to the
entire printed page and this option has no affect.
EXAMPLES
The following generates POSTSCRIPT Level 2 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.)
If you have a long image, it may be splitted in several
pages:
tiff2ps -h11 -w8.5 -H14 -L.5 foo.tif > foo.ps
The page size is set to 8.5x11 by -w and -h options. We will
accept a small amount of vertical compression, so -H set to
14. Any pages between 11 and 14 inches will be fit onto one
page. Pages longer than 14 inches are cut off at 11 and
continued on the next page. The -L.5 option says to repeat a
half inch on the next page (to improve readability).
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 handle tiled images when generating PS Level I out-
put.
