NAME

       SWF::Filter - SWF filter class

SYNOPSIS

               use SWF::Blur;
               use SWF::Shadow;
               use SWF::Constants qw(:Filter);
               @color= (12,45,99);
               $blur = new SWF::Blur(15, 15, 2);
               $shadow = new SWF::Shadow(2.5, 12, 2);
               $filter = SWF::Filter::newDropShadowFilter( \@color,
                         $blur, $shadow, SWF_FILTER_MODE_KO);
               $displayitem->addFilter( $filter);

DESCRIPTION

       Filter objects are available since player version 8. They can be applied to buttons,
       movieclips and text instances by the addFilter() method of SWF::DisplayItem objects.
       Several types of filters exist. Each of them has its own method of construction, see
       below.

METHODS

       newDropShadowFilter($colorref, $blur, $shadow, $flags)
           Creates a DropShadowFilter object. The object is controlled by color, blur object,
           shadow object and flags (SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO).

       newBlurFilter($blur)
           Creates a BlurFilter object. The object is controlled by the blur object.

       newGlowFilter($colorref, $blur, $strength, $flags)
           Creates a GlowFilter object, a simple variant of DropShadowFilter.  Use
           SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO as flag values.

       newBevelFilter($shadow_colorref, $highlight_colorref, $blur, $shadow, $flags)
           Just another (complex) variant of DropShadowFilter.  Use SWF_FILTER_MODE_INNER,
           SWF_FILTER_MODE_KO or FILTER_MODE_ONTOP as flag values.

       newGradientGlowFilter($gradient, $blur, $shadow, $flags)
           Just another (more complex) variant of DropShadowFilter.  As flag use
           SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO or SWF_FILTER_MODE_ONTOP .

       newGradientBevelFilter($gradient, $blur, $shadow, $flags)
           Just another (slightly more complex) variant of DropShadowFilter, extending
           newBevelFilter() by using a gradient instead of simple colors.  Use
           SWF_FILTER_MODE_INNER, SWF_FILTER_MODE_KO or FILTER_MODE_ONTOP as flag values.

       newColorMatrixFilter($filtermatrix)
           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.

       newConvolutionFilter($filtermatrix, $divisor, $bias, $colorref, $flags)
           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.
