<p><i>tiff2ps</i> reads <small>TIFF</small> images and
writes P <small>OST</small> S <small>CRIPT</small> or
Encapsulated P <small>OST</small> S <small>CRIPT</small>
(EPS) on the standard output. By default, <i>tiff2ps</i>
writes Encapsulated P <small>OST</small> S
<small>CRIPT</small> for the first image in the specified
<small>TIFF</small> image file.</p>
<!-- INDENTATION -->
<p>By default, <i>tiff2ps</i> will generate P
<small>OST</small> S <small>CRIPT</small> that fills a
printed area specified by the <small>TIFF</small> tags in
the input file. If the file does not contain
<i>XResolution</i> or <i>YResolution</i> tags, then the
printed area is set according to the image dimensions. The
<b>&minus;w</b> and <b>&minus;h</b> options (see below) can
be used to set the dimensions of the printed area in inches;
overriding any relevant <small>TIFF</small> tags.</p>
<!-- INDENTATION -->
<p>The P <small>OST</small> S <small>CRIPT</small> generated
for <small>RGB,</small> palette, and <small>CMYK</small>
images uses the <i>colorimage</i> operator. The P
<small>OST</small> S <small>CRIPT</small> generated for
greyscale and bilevel images uses the <i>image</i> operator.
When the <i>colorimage</i> operator is used, P
<small>OST</small> S <small>CRIPT</small> code to emulate
this operator on older P <small>OST</small> S
<small>CRIPT</small> printers is also generated. Note that
this emulation code can be very slow.</p>

<p>Color images with associated alpha data are composited

<p>Because P <small>OST</small> S <small>CRIPT</small> does
not support the notion of a colormap, 8-bit palette images
produce 24-bit P <small>OST</small> S <small>CRIPT</small>
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.</p>
