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.
