  • Constructor Details

    • ShadowFilter

      public ShadowFilter()
      Construct a ShadowFilter.

    • ShadowFilter

      public ShadowFilter(float radius, float xOffset, float yOffset, float opacity)
      Construct a ShadowFilter.
      Parameters:
      radius - the radius of the shadow
