  • IlvValueGradientPaint(IlvChart, int, double[], Color[], short, boolean): Creates a gradient based on the specified y-values.
  • IlvValueGradientPaint(IlvChart, double[], Color[], short, boolean): Creates a gradient based on the specified x-values.


• New methods:
  • createPlaneRestrictedPaint(Ilv3DTransform, Ilv3DVector, double): Creates and returns a Paint that can be used to generate the color pattern for a piece of the scene that lies on a given plane.
  • getPixelARGB(int, int, double, double, double, double, double, double): Returns the color, as an ARGB-encoded integer, of the given pixel.
