TIFF2PS(1)TIFF2PS(1)NAMEtiff2ps - convert a TIFF image to POSTSCRIPT
SYNOPSIStiff2ps [ options ] input.tif ...
DESCRIPTIONtiff2ps reads TIFF images and writes POSTSCRIPT or Encap
sulated 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
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 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 col
ormap, 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.
