javax.media.jai.operator.OrderedDitherDescriptor
| OrderedDitherDescriptor | | public class OrderedDitherDescriptor extends OperationDescriptorImpl (Code) | | An OperationDescriptor describing the "OrderedDither"
operation.
The "OrderedDither" operation performs color quantization by
finding the nearest color to each pixel in a supplied color cube
and "shifting" the resulting index value by a pseudo-random amount
determined by the values of a supplied dither mask.
The dither mask is supplied as an array of KernelJAI
objects the length of which must equal the number of bands in the
image. Each element of the array is a KernelJAI object
which represents the dither mask matrix for the corresponding band.
All KernelJAI objects in the array must have the same
dimensions and contain floating point values greater than or equal
to 0.0 and less than or equal to 1.0.
For all integral data types, the source image samples are presumed
to occupy the full range of the respective types. For floating point data
types it is assumed that the data samples have been scaled to the range
[0.0, 1.0].

| OrderedDitherDescriptor | | public OrderedDitherDescriptor()(Code) | | Constructor.
|
| validateArguments | | public boolean validateArguments(String modeName, ParameterBlock args, StringBuffer msg)(Code) | | Validates the input source and parameters.
In addition to the standard checks performed by the
superclass method, this method checks that "colorMap"
and "ditherMask" are valid for the given source image.
