# 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.
