page: `docbook-to-man manpage.sgml > manpage.1'. You may view
the manual page with: `docbook-to-man manpage.sgml | nroff -man |

Please remember that if you create the nroff version in one of the
debian/rules file targets (such as build), you will need to include
docbook-to-man in your Build-Depends control field.

<title>DESCRIPTION</title>
<para>Reads an image which is already available in memory. The parameter
<parameter>source</parameter> is currently not evaluated and assumed
to be `memory'. The parameter <parameter>type</parameter> can be either
`raw' or `eps'. Images in raw format are expected to be a stream of pixels
starting in the upper left and ending in the lower right corner. Each
pixel is a tuple of components representing the colors. Each component
consists of <parameter>bpc</parameter> bit. Color imgags expect the
components to be stored in RGB or CMYK order. The number of components
implies the colorspace. 4 components imply a CMYK image and not an
RGB image with an alpha channel. This restriction may be removed in
later versions.</para>
<para>EPS images are expect as stored in a file. There is no need to
set any other paramter. The height und width of the image is
taken from the bounding box within the image data.</para>
<para>Since version 0.4.5 of pslib images are read by default for later
reuse. This means that the image is saved into a so called reusable
stream object. Later calls of <function>PS_place_image(3)</function>
will only put a short
sequence of postscript code into the output file replaying the image.
This reduces the overall postscript file size, speeds up its processing by
the postscript rip and allows to place images into templates. This
behaviour can be turned off by setting the parameter `imagereuse'
to false with <function>PS_set_parameter(3)</function>.</para>

<title>RETURN VALUE</title>
<para>Returns identifier of the image or zero in case of an error.
The identifier is a positiv number greater 0.</para>
