tiff2ps − convert a <small>TIFF</small> image to

PostScript™

SYNOPSIS

       cols="2" cellspacing="0" cellpadding="0">

tiff2ps [ options ] input.tif

...

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

tiff2ps reads <small>TIFF</small> 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

<small>TIFF</small> image file.

By default, tiff2ps will generate PostScript that

fills a printed area specified by the <small>TIFF</small>

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 <small>TIFF</small> tags.

The PostScript generated for <small>RGB,</small> palette,

and <small>CMYK</small> 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

       cols="5" cellspacing="0" cellpadding="0">

−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.

−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 <small>TIFF</small> 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 (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

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 <small>TIFF</small> directory to the

<small>IFD</small> 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.

−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 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

       cols="2" cellspacing="0" cellpadding="0">

The following generates PostScript Level 2 for all pages

of a facsimile:

       cols="2" cellspacing="0" cellpadding="0">

tiff2ps −a2 fax.tif | lpr

       cols="2" cellspacing="0" cellpadding="0">

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:

       cols="2" cellspacing="0" cellpadding="0">

tiff2ps −d 1 foo.tif

       cols="2" cellspacing="0" cellpadding="0">

(Notice that directories are numbered starting at

zero.)

If you have a long image, it may be split in several

pages:

       cols="2" cellspacing="0" cellpadding="0">

tiff2ps −h11 −w8.5 −H14 −L.5 foo.tif > foo.ps

       cols="2" cellspacing="0" cellpadding="0">

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

       cols="2" cellspacing="0" cellpadding="0">

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.
