javax.media.jai.ImageMIPMap

A class implementing the "MIP map" operation on a RenderedImage. Given a RenderedImage, which represents the image at the highest resolution level, the image at each lower resolution level may be derived by performing a specific chain of operations to down sample the image at the next higher resolution level repeatedly. The highest resolution level is defined as level 0.

The downSampler is a chain of operations that is used to derive the image at the next lower resolution level from the image at the current resolution level. That is, given an image at resolution level i, the downSampler is used to obtain the image at resolution level i+1. The chain may contain one or more operation nodes; however, each node must be a RenderedOp. The parameter points to the last node in the chain. The very first node in the chain must be a RenderedOp that takes one RenderedImage as its source. All other nodes may have multiple sources. When traversing back up the chain, if a node has more than one source, the first source, source0, is used to move up the chain. This parameter is saved by reference. @see ImagePyramid

            float minX = paramBlock.getFloatParameter(2);
            float minY = paramBlock.getFloatParameter(3);
            float height = paramBlock.getFloatParameter(4);


            // Create an image pyramid.
            ImageMIPMap pyramid = new ImageMIPMap(source, downSampler);


            // Create a Vector of RenderedImages from the pyramid.
            Vector sourceVector = new Vector();
            RenderedImage currentImage = pyramid.getCurrentImage();
            sourceVector.add(currentImage);
            while(currentImage.getWidth() > maxLowResDim ||
                  currentImage.getHeight() > maxLowResDim) {
                RenderedImage nextImage = pyramid.getDownImage();
                if(nextImage.getWidth() >= currentImage.getWidth() ||
                   nextImage.getHeight() >= currentImage.getHeight()) {
                    throw new IllegalArgumentException(JaiI18N.getString("RenderableCRIF0"));
                }
                sourceVector.add(nextImage);
