flash.filters 

The flash.filters package contains classes for bitmap filter effects. Filters let you apply rich visual effects, such as blur, bevel, glow, and drop shadows, to display objects.



Classes
 ClassDescription
 BevelFilter The BevelFilter class lets you add a bevel effect to display objects.
 BitmapFilter The BitmapFilter class is the base class for all image filter effects.
 BitmapFilterQuality The BitmapFilterQuality class contains values to set the rendering quality of a BitmapFilter object.
 BitmapFilterType The BitmapFilterType class contains values to set the type of a BitmapFilter.
 BlurFilter The BlurFilter class lets you apply a blur visual effect to display objects.
 ColorMatrixFilter The ColorMatrixFilter class lets you apply a 4 x 5 matrix transformation on the RGBA color and alpha values of every pixel in the input image to produce a result with a new set of RGBA color and alpha values.
 ConvolutionFilter The ConvolutionFilter class applies a matrix convolution filter effect.
 DisplacementMapFilter The DisplacementMapFilter class uses the pixel values from the specified BitmapData object (called the displacement map image) to perform a displacement of an object.
 DisplacementMapFilterMode The DisplacementMapFilterMode class provides values for the mode property of the DisplacementMapFilter class.
 DropShadowFilter The DropShadowFilter class lets you add a drop shadow to display objects.
 GlowFilter The GlowFilter class lets you apply a glow effect to display objects.
 GradientBevelFilter The GradientBevelFilter class lets you apply a gradient bevel effect to display objects.
 GradientGlowFilter The GradientGlowFilter class lets you apply a gradient glow effect to display objects.
 ShaderFilter The ShaderFilter class applies a filter by executing a shader on the object being filtered.
