Example 12 with RenderedImage

use of java.awt.image.RenderedImage in project jdk8u_jdk by JetBrains.

the class RenderableImageOp method createRendering.

/**
     * Creates a RenderedImage which represents this
     * RenderableImageOp (including its Renderable sources) rendered
     * according to the given RenderContext.
     *
     * <p> This method supports chaining of either Renderable or
     * RenderedImage operations.  If sources in
     * the ParameterBlock used to construct the RenderableImageOp are
     * RenderableImages, then a three step process is followed:
     *
     * <ol>
     * <li> mapRenderContext() is called on the associated CRIF for
     * each RenderableImage source;
     * <li> createRendering() is called on each of the RenderableImage sources
     * using the backwards-mapped RenderContexts obtained in step 1,
     * resulting in a rendering of each source;
     * <li> ContextualRenderedImageFactory.create() is called
     * with a new ParameterBlock containing the parameters of
     * the RenderableImageOp and the RenderedImages that were created by the
     * createRendering() calls.
     * </ol>
     *
     * <p> If the elements of the source Vector of
     * the ParameterBlock used to construct the RenderableImageOp are
     * instances of RenderedImage, then the CRIF.create() method is
     * called immediately using the original ParameterBlock.
     * This provides a basis case for the recursion.
     *
     * <p> The created RenderedImage may have a property identified
     * by the String HINTS_OBSERVED to indicate which RenderingHints
     * (from the RenderContext) were used to create the image.
     * In addition any RenderedImages
     * that are obtained via the getSources() method on the created
     * RenderedImage may have such a property.
     *
     * @param renderContext The RenderContext to use to perform the rendering.
     * @return a RenderedImage containing the desired output image.
