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.
