+--javax.media.jai.operator.ErrorDiffusionDescriptor
- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class ErrorDiffusionDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "ErrorDiffusion"
operation.
The "ErrorDiffusion" operation performs color quantization by
finding the nearest color to each pixel in a supplied color map
and "diffusing" the color quantization error below and to the right
of the pixel.

ErrorDiffusionDescriptor
public ErrorDiffusionDescriptor()
- Constructor.
create
public static RenderedOp create(RenderedImage source0,
LookupTableJAI colorMap,
KernelJAI errorKernel,
RenderingHints hints)
- Performs error diffusion color quantization using a specified color map and error filter.
Creates a ParameterBlockJAI from all
supplied arguments except hints and invokes
JAI.create(String,ParameterBlock,RenderingHints).
- Parameters:
source0 - RenderedImage source 0.colorMap - The color map.errorKernel - The error filter kernel.
May be null.hints - The RenderingHints to use.
May be null.- Returns:
- The
RenderedOp destination. - Throws:
IllegalArgumentException - if source0 is null.IllegalArgumentException - if colorMap is null.- See Also:
