<h1><a name="description">DESCRIPTION</a></h1>
<p>SWF::FilterMatrix is a helper class useful for construction
of some SWF::Filter objects: ColorMatrix filter and Convolution filter.</p>
<p>
</p>
<hr />
<h1><a name="methods">METHODS</a></h1>
<dl>
<dt><strong><a name="filtermatrix" class="item">new SWF::FilterMatrix($cols, $rows, $valueref)</a></strong>
<dd>
<p>The only method is a constructor for creation of
a FilterMatrix object. The object is controlled by
the matrix data dimensions (cols * rows) and the
data values: a reference to an array of float values.
Note: constructing ColorMatrixFilter needs a 5*4 matrix.</p>
