tiff2ps - convert a TIFF image to POSTSCRIPTtm
tiff2ps [ options ] input.tif ...
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; 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 POST-
SCRIPT 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.
-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
-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 gener-
ated, data is imaged to the entire printed page and this option has no affect.
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.)
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 PS Level I output.
