tiff2ps(1)
NAME
tiff2ps - convert a TIFF image to PostScript
SYNOPSIS
tiff2ps [ options ] input.tif ...
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.
-8 Disable use of ASCII85 encoding with PostScript Level 2/3.
-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.
-C Specify the document creator name.
-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.
-D Enable duplex printing (two pages per sheet of paper).
-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. -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 and -W options.
-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.
-O Write PostScript to specified file instead of standard output.
-p Force the generation of (non-Encapsulated) PostScript.
-P L|P Set optional PageOrientation DSC comment to Landscape or
Portrait.
-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.
-t Specify the document title string.
-T Print pages for top edge binding.
-w Specify the horizontal size of the printed area (in inches).
-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.
-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.
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).
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.
