.SH NAME

tiff2ps \- convert a

.SM TIFF

image to \*(Ps\*(Tm

.SH SYNOPSIS

.B tiff2ps

[

.I options

]

.I "input.tif ..."

.SH DESCRIPTION

.I tiff2ps

reads

.SM TIFF

images and writes \*(Ps or Encapsulated \*(Ps (EPS)

on the standard output.

By default,

.I tiff2ps

writes Encapsulated \*(Ps for the first image in the specified

.SM TIFF

image file.

.PP

By default,

.I tiff2ps

will generate \*(Ps that fills a printed area specified

by the 

.SM TIFF

tags in the input file.

If the file does not contain

.I XResolution

or

.I YResolution

tags, then the printed area is set according to the image dimensions.

The

.B \-w

and

.B \-h

options (see below)

can be used to set the dimensions of the printed area in inches;

overriding any relevant

.SM TIFF

tags.

.PP

The \*(Ps generated for

.SM RGB,

palette, and

.SM CMYK

images uses the

.I colorimage

operator.

The \*(Ps generated for

greyscale and bilevel images

uses the

.I image

operator.

When the

.I 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.

.PP

Color images with associated alpha data are composited over

a white background.

.SH OPTIONS

.TP

.B \-1

Generate \*(Ps Level 1 (the default).

.TP

.B \-2

Generate \*(Ps Level 2.

.TP

.B \-3

Generate \*(Ps Level 3. It basically allows one to use the /flateDecode

filter for ZIP compressed TIFF images.

.TP

.B \-a

Generate output for all IFDs (pages) in the input file.

.TP

.B \-b

Specify the bottom margin for the output (in inches). This does not affect

the height of the printed image.

.TP

.B \-c

Center the image in the output. This option only shows an effect if both

the

.B \-w

and the

.B \-h

option are given.

.TP

.B \-d

Set the initial

.SM 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.

.TP

.B \-e

Force the generation of Encapsulated \*(Ps (implies

.BR \-z ).

.TP

.B \-h

Specify the vertical size of the printed area (in inches).

.TP

.B \-H

Specify the maximum height of image (in inches). Images with larger sizes will

be split in several pages. Option

.B \-L

may be used for specifying size of split images overlapping.

.TP

.B \-W

Specify the maximum width of image (in inches). Images with larger sizes will

be split in several pages. Options

.B \-L

and 

.B \-W

are mutually exclusive.

.B \-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.

.TP

.B \-L

Specify the size of overlapping for split images (in inches). Used in

conjunction with

.B \-H

option and

.B \-W

option.

.TP

.B \-l

Specify the left margin for the output (in inches). This does not affect

the width of the printed image.

.TP

.B \-m

Where possible render using the

.I imagemask

\*(Ps operator instead of the

.I image

operator.  When this option is specified

.I tiff2ps

will use

.I imagemask

for rendering 1 bit deep images.  If this option is not specified

or if the image depth is greater than 1 then the

.I image

operator is used.

.TP

.B \-o

Set the initial

.SM TIFF

directory to the

.SM IFD

at the specified file offset.

This option is useful for selecting thumbnail images and the

like which are hidden using the

.I SubIFD

tag.

.TP

.B \-p

Force the generation of (non-Encapsulated) \*(Ps.

.TP

.B \-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.

.TP

.B \-s

Generate output for a single IFD (page) in the input file.

.TP

.B \-w

Specify the horizontal size of the printed area (in inches).

.TP

.B \-x

Override resolution units specified in the TIFF as centimeters.

.TP

.B \-y

Override resolution units specified in the TIFF as inches.

.TP

.B \-z

When generating \*(Ps Level 2, data is scaled so that it does not

image into the 

.I 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.

.SH EXAMPLES

The following generates \*(Ps Level 2 for all pages of a facsimile:

.RS

.nf

tiff2ps \-a2 fax.tif | lpr

.fi

.RE

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.

.PP

To generate Encapsulated \*(Ps for a the image at directory 2

of an image use:

.RS

.nf

tiff2ps \-d 1 foo.tif

.fi

.RE

(Notice that directories are numbered starting at zero.)

.PP

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

.RS

.nf

tiff2ps \-h11 \-w8.5 \-H14 \-L.5 foo.tif > foo.ps

.fi

.RE

The page size is set to 8.5x11 by

.B \-w

and

.B \-h

options. We will accept a small amount of vertical compression, so

.B \-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

.B \-L.5

option says to repeat a half inch on the next page (to improve readability).

.SH BUGS

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.

.PP

Does not handle tiled images when generating \*(Ps Level I output.
