tiff2ps - convert a TIFF
image to Pstm
tiff2ps
[ options ] input.tif ...
tiff2ps reads TIFF
images and writes Ps
or Encapsulated Ps (EPS) on the standard output. By default, tiff2ps writes
Encapsulated Ps for the first image in the specified TIFF
image file.
By
default, tiff2ps will generate Ps 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 Ps
generated for RGB,
palette, and CMYK
images uses the colorimage operator.
The Ps generated for greyscale and bilevel images uses the image operator.
When the colorimage operator is used, Ps code to emulate this operator
on older Ps 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 Ps Level 1 (the default).
- -2
- Generate
Ps Level 2.
- -3
- Generate Ps 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 Ps (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.
- -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.
- -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 Ps 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) Ps.
- -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 centimeters.
- -y
- Override resolution units specified
in the TIFF as inches.
- -z
- When generating Ps 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 Ps Level 1 is generated, data is imaged to the entire printed page
and this option has no affect.
The following generates Ps 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 Ps 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).
Because Ps does
not support the notion of a colormap, 8-bit palette images produce 24-bit
Ps 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.
