<!-- Process this file with docbook-to-man to generate an nroff manual
     page: `docbook-to-man manpage.sgml > manpage.1'.  You may view
     the manual page with: `docbook-to-man manpage.sgml | nroff -man |
     less'.  A typical entry in a Makefile or Makefile.am is:

manpage.1: manpage.sgml
	docbook-to-man $< > $@

    
	The docbook-to-man binary is found in the docbook-to-man package.
	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>

    <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>
