Examples of org.eclipse.jface.resource.CompositeImageDescriptor

org.eclipse.jface.resource.CompositeImageDescriptor
Abstract base class for image descriptors that synthesize an image from other images in order to simulate the effect of custom drawing. For example, this could be used to superimpose a red bar dexter symbol across an image to indicate that something was disallowed.
Subclasses must implement the getSize and fill methods. Little or no work happens until the image descriptor's image is actually requested by a call to createImage (or to getImageData directly).

        Image result = decoratedMap.get(decorator);
        if (result == null) {
            final Rectangle bib = baseImage.getBounds();
            final Rectangle dib = decorator.getBounds();
            final Point baseImageSize = new Point(bib.width, bib.height);
            final CompositeImageDescriptor compositImageDesc = new CompositeImageDescriptor() {
                @Override
                protected void drawCompositeImage(final int width, final int height) {
                    drawImage(baseImage.getImageData(), 0, 0);
                    if (corner == TOP_LEFT) {
                        drawImage(decorator.getImageData(), 0, 0);
                    } else if (corner == TOP_RIGHT) {
                        drawImage(decorator.getImageData(), bib.width - dib.width, 0);
                    } else if (corner == BOTTOM_LEFT) {
                        drawImage(decorator.getImageData(), 0, bib.height - dib.height);
                    } else if (corner == BOTTOM_RIGHT) {
                        drawImage(decorator.getImageData(), bib.width - dib.width,
                                bib.height - dib.height);
                    }
                }


                @Override
                protected Point getSize() {
                    return baseImageSize;
                }
