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 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.)
If you have a long image, it may be split 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).

description
tiff2ps
reads TIFF images and writes PostScript or
Encapsulated 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; 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 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 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 (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 split in several pages. Option
-L may be used for specifying size of split
images overlapping.
-W
Specify the maximum width of image (in inches). Images
with larger sizes will be split in several pages. Options
-L and -W are mutually exclusive.
-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 split images (in
inches). Used in conjunction with -H option and
-W 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 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.
-r
90|180|270|auto
Rotate image by 90, 180, 270
degrees or auto. Auto picks the best fit for the image on
the specified paper size (eg portrait or landscape) if -h or
-w is specified. Rotation is in degrees counterclockwise.
Auto rotates 90 degrees ccw to produce landscape.
-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
centimeters.
-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 behavior. When PostScript
Level 1 is generated, data is imaged to the entire printed
page and this option has no affect.
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.
Does not handle
tiled images when generating PostScript Level I output.
