<p><i>tiff2ps</i> reads <small>TIFF</small> images and
writes PostScript or Encapsulated PostScript (EPS) on the
standard output. By default, <i>tiff2ps</i> writes
Encapsulated PostScript for the first image in the specified
<small>TIFF</small> image file.</p>
<!-- INDENTATION -->
<p>By default, <i>tiff2ps</i> 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
<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 PostScript generated for <small>RGB,</small> palette,
and <small>CMYK</small> images uses the <i>colorimage</i>
operator. The PostScript generated for greyscale and bilevel
images uses the <i>image</i> operator. When the
<i>colorimage</i> 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.</p>
<!-- INDENTATION -->
<p>Color images with associated alpha data are composited
over a white background.</p>

(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.</p>

vertical compression, so <b>&minus;H</b> set to 14. Any

<p>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.</p>
