The BitmapFilter class is the base class for all image filter effects.

The BlurFilter class lets you apply a blur visual effect to display objects. A blur effect softens the details of an image. You can produce blurs that range from a softly unfocused look to a Gaussian blur, a hazy appearance like viewing an image through semi-opaque glass. When the quality property of this filter is set to low, the result is a softly unfocused look. When the quality property is set to high, it approximates a Gaussian blur filter. You can apply the filter to any display object (that is, objects that inherit from the DisplayObject class), such as MovieClip, SimpleButton, TextField, and Video objects, as well as to BitmapData objects.

The GlowFilter class lets you apply a glow effect to display objects. You have several options for the style of the glow, including inner or outer glow and knockout mode. The glow filter is similar to the drop shadow filter with the distance and angle properties of the drop shadow filter set to 0. You can apply the filter to any display object (that is, objects that inherit from the DisplayObject class), such as MovieClip, SimpleButton, TextField, and Video objects, as well as to BitmapData objects.

The ShaderFilter class applies a filter by executing a shader on the object being filtered. The filtered object is used as an input to the shader, and the shader output becomes the filter result.
