.SH NAME
tiff2ps \- convert TIFF image to PostScript™
.SH SYNOPSIS
.sp
\fBtiff2ps\fP [ \fIoptions\fP ] \fIinput.tif\fP …
.SH DESCRIPTION
.sp
\fBtiff2ps\fP reads TIFF images and writes PostScript™ or Encapsulated
PostScript™ (EPS) on the standard output. By default \fBtiff2ps\fP
writes Encapsulated PostScript™ for the first image in the specified
TIFF image file.
.sp
By default, \fBtiff2ps\fP will generate PostScript™ that fills a
printed area specified by the TIFF tags in the input file.
If the file does not contain \fBXResolution\fP or \fBYResolution\fP
tags, then the printed area is set according to the image dimensions.
The \fI\%\-w\fP and \fI\%\-h\fP options (see below)
can be used to set the dimensions of the printed area in inches;
overriding any relevant TIFF tags.
.sp
The PostScript™ generated for RGB, palette, and CMYK images uses the
\fBcolorimage\fP operator.  The PostScript™ generated for greyscale and
bilevel images uses the \fBimage\fP operator.  When the \fBcolorimage\fP
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.
.sp
Color images with associated alpha data are composited over
a white background.

Specify the vertical size of the printed area (in inches).
.UNINDENT
.INDENT 0.0

be split in several pages. Option \fI\%\-L\fP
may be used for specifying size of split images overlapping.
.UNINDENT

single numeric value: zero to disable pixel interpolation and
non\-zero to enable.  The default is enabled.

Set to 0 to disable the limit.
.UNINDENT
.INDENT 0.0
.TP
.B \-m
Where possible render using the \fBimagemask\fP PostScript™ operator instead of the
\fBimage\fP operator.  When this option is specified \fBtiff2ps\fP will use
\fBimagemask\fP for rendering 1 bit deep images.  If this option is not specified
or if the image depth is greater than 1 then the \fBimage\fP operator is used.
.UNINDENT
.INDENT 0.0
.TP
.B \-o ifdoffset
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 \fBSubIFD\fP tag.
.UNINDENT
.INDENT 0.0
.TP
.B \-O
Write PostScript™ to specified file instead of standard output.

When generating PostScript™ Level 2, data is scaled so that it does not
image into the \fBdeadzone\fP 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.
.UNINDENT
.SH EXAMPLES
.sp
The following generates PostScript™ Level 2 for all pages of a facsimile:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
tiff2ps \e\-a2 fax.tif | lpr
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
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.
.sp
To generate Encapsulated PostScript™ for a the image at directory 2
of an image use:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
tiff2ps \e\-d 1 foo.tif
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
(Notice that directories are numbered starting at zero.)
.sp
If you have a long image, it may be split in several pages:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
tiff2ps \e\-h11 \e\-w8.5 \e\-H14 \e\-L.5 foo.tif > foo.ps
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
The page size is set to 8.5x11 by \fI\%\-w\fP and \fI\%\-h\fP
options. We will accept a small amount of vertical compression, so
\fI\%\-H\fP 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 \fB\-L.5\fP
option says to repeat a half inch on the next page (to improve readability).
.SH BUGS
.sp
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.
.sp
Does not handle tiled images when generating PostScript™ Level I output.
