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.
