    • create

      public static javax.media.jai.RenderedOp create(RenderedImage source, double factor, double offset, ScalingType scalingType, InterpretationType interpretationType, RenderingHints hints)
      Reinterprets an image.

      Creates a ParameterBlockJAI from all supplied arguments (except hints) and invokes JAI.create(String,java.awt.image.renderable.ParameterBlock,java.awt.RenderingHints).

      Parameters:
      source - The RenderedImage source.
      factor - The scaling factor.
      offset - The scaling offset.
      scalingType - The manner of scaling.
      interpretationType - The interpretation type.
      hints - The RenderingHints to use. May be null.
      Returns:
      The RenderedOp destination.
      Throws:
      IllegalArgumentException - if source is null.
