Class ReinterpretDescriptor

  • All Implemented Interfaces:
    Serializable, javax.media.jai.OperationDescriptor, javax.media.jai.RegistryElementDescriptor
    public class ReinterpretDescriptor
extends javax.media.jai.OperationDescriptorImpl
    An OperationDescriptor describing the "Reinterpret" operation.

    The Reinterpret operation creates a single-banded, tiled rendered image, where the source samples are rescaled or reformatted.

    • Field Detail

      • AWT

        public static final InterpretationType AWT
        The default interpretation type: all data types are interpreted as in AWT

      • INTERPRET_BYTE_SIGNED

        public static final InterpretationType INTERPRET_BYTE_SIGNED
        Interpretation type for interpreting byte data as signed.

      • INTERPRET_INT_UNSIGNED

        public static final InterpretationType INTERPRET_INT_UNSIGNED
        Interpretation type for interpreting integer data as unsigned.

      • LINEAR

        public static final ScalingType LINEAR
        The default scaling type: source samples are scaled linearly.

      • EXPONENTIAL

        public static final ScalingType EXPONENTIAL
        Exponential scaling type: source samples are scaled linearly and then raised to the power of 10.

      • LOGARITHMIC

        public static final ScalingType LOGARITHMIC
        Logarithmic scaling type: source samples are scaled linearly and then their logarithms to the basis of 10 are computed.

      • create

        public static javax.media.jai.RenderedOp create​(RenderedImage source,
                                                double factor,

        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.
