<h1><a name="description">DESCRIPTION</a></h1>
<p>Filter objects are available since player version 8. They can be applied to buttons, movieclips and text instances
by the <code>addFilter()</code> method of SWF::DisplayItem objects. Several types of filters exist. Each of them
has its own method of construction, see below.</p>

<h1><a name="methods">METHODS</a></h1>
<dl>
<dt><strong><a name="newdropshadowfilter" class="item">newDropShadowFilter($colorref, $blur, $shadow, $flags)</a></strong>
<dd>
<p>Creates a DropShadowFilter object. The object is controlled by color, blur object,
shadow object and flags (SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO).</p>
</dd>
</li>
<dt><strong><a name="newblurfilter" class="item"><code>newBlurFilter($blur)</code></a></strong>
<dd>
<p>Creates a BlurFilter object. The object is controlled by the blur object.</p>
</dd>
</li>
<dt><strong><a name="newglowfilter" class="item">newGlowFilter($colorref, $blur, $strength, $flags)</a></strong>
<dd>
<p>Creates a GlowFilter object, a simple variant of DropShadowFilter.
Use SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO as flag values.</p>
</dd>
</li>
<dt><strong><a name="newbevelfilter" class="item">newBevelFilter($shadow_colorref, $highlight_colorref, $blur, $shadow, $flags)</a></strong>
<dd>
<p>Just another (complex) variant of DropShadowFilter.
Use SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO or
FILTER_MODE_ONTOP as flag values.</p>
</dd>
</li>
<dt><strong><a name="newgradientglowfilter" class="item">newGradientGlowFilter($gradient, $blur, $shadow, $flags)</a></strong>
<dd>
<p>Just another (more complex) variant of DropShadowFilter.
As flag use SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO
or SWF_FILTER_MODE_ONTOP .</p>
</dd>
</li>
<dt><strong><a name="newgradientbevelfilter" class="item">newGradientBevelFilter($gradient, $blur, $shadow, $flags)</a></strong>
<dd>
<p>Just another (slightly more complex) variant of DropShadowFilter,
extending <a href="#newbevelfilter"><code>newBevelFilter()</code></a> by using a gradient instead of simple colors.
Use SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO or FILTER_MODE_ONTOP
as flag values.</p>
</dd>
</li>
<dt><strong><a name="newcolormatrixfilter" class="item"><code>newColorMatrixFilter($filtermatrix)</code></a></strong>
<dd>
<p>The filtermatrix is an object of SWF::FilterMatrix class sized 5 columns x 4 rows
for RGBA values, useful for transformations like color conversion to
greyscale pictures.</p>
</dd>
</li>
<dt><strong><a name="newconvolutionfilter" class="item">newConvolutionFilter($filtermatrix, $divisor, $bias, $colorref, $flags)</a></strong>
<dd>
<p>Another filter for nice picture effects like blur etc.
The filtermatrix is an object of SWF::FilterMatrix class.
As flag use either use SWF_FILTER_FLAG_CLAMP or SWF_FILTER_FLAG_PRESERVE_ALPHA.</p>
</dd>
