Deprecated. Replaced by Hints.

public final class Hints

extends java.awt.RenderingHints.Key

A set of RenderingHints keys for grid coverage operations. Hints are memorized by GridCoverageProcessor, which formard them to Operation.doOperation(javax.media.jai.ParameterList, java.awt.RenderingHints) at every invocation. Rendering hints can be used to control some low-level details, like the JAI instance to use when performing operation. Operations may use the hints or ignore them.

For example, if a user wants to use the "Resample" operation with a custom CoordinateTransformation, he should first create its own CoordinateTransformationFactory implementation. Then, he can create a GridCoverageProcessor with its factory as a rendering hint:

 CoordinateTransformationFactory myFactory = ...
 RenderingHints hints = new RenderingHints(Hints.COORDINATE_TRANSFORMATION_FACTORY, myFactory);
 GridCoverageProcessor processor = new GridCoverageProcessor(hints);
