NAME
tiff2ps - convert a
TIFF
image to POSTSCRIPTtm
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 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).
- -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 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.
BUGS
Does not handle tiled images when generating PS Level I output.
