Description

BlurFilterParams describes arguments for a Blur filter implementation. These arguments describe a blur filter state and are also passed into HAL. Filter parameter (BlurX/Y, Offset) coordinate system must match that of a shape and/or text-field that is applied to.

Data Members

Data Member	Description
BlurX	The amount of horizontal blur. // in Twips
BlurY	The amount of vertical blur. // In Twips
Colors	Color of the drop shadow. // Color[0] = Shadow color, Color [1] = Highlight color
Gradient	Gradient, for GradientGlowFilter and GradientBevelFilter (null otherwise)
Mode	The supported filter mode. // Combination of ModeConstants and FilterType.
Offset	Offset of the drop shadow.
Passes	The number of times to perform the blur.
Strength	The intensity of the filter applied. [0...1

Enumerations
