MaskFilter(native)

MaskFilter is the base class for object that perform transformations on an alpha-channel mask before drawing it.

Methods

  • blur(radius, styleSymbol, flagsSymbol) : MaskFilter
    Blur the image using different styles.

Remarks

A subclass of MaskFilter may be installed into a Paint. Once there, each time a primitive is drawn, it is first scan converted into a #kA8_Format mask, and handed to the filter, calling its filterMask() method. If this returns true, then the new mask is used to render into the device.
