Examples of java.awt.RenderingHints$Key

java.awt.RenderingHints
Defines the base type of all keys used along with the {@link RenderingHints} class to control variousalgorithm choices in the rendering and imaging pipelines. Instances of this class are immutable and unique which means that tests for matches can be made using the {@code ==} operator instead of the more expensive{@code equals()} method.

        if (instance == null) {
            throw new ImagingException(JaiI18N.getString("RemoteRenderedOp2"));
        }


  // Save the state of the node.
  RenderingHints rh = nodeSupport.getRenderingHints();
        oldHints = rh == null ? null : (RenderingHints)rh.clone();


  // Ensure that the rendering is a PlanarImage.
        return PlanarImage.wrapRenderedImage(instance);
