Class ZiggyImapRenderer

  • All Implemented Interfaces:
    java.io.Serializable, FeatureRenderer, ImageMapRenderer

    public class ZiggyImapRenderer
    extends java.lang.Object
    implements ImageMapRenderer, java.io.Serializable

    ZiggyImapRenderer is a decorator for ZiggyFeatureRenderer which adds the ability to create HTML image map coordinates which correspond to the feature rendering produced by the ZiggyFeatureRenderer. These coordinates correspond to the block regions of the image rather than the "elbow" sections which join the locations.

      • ZiggyImapRenderer

        public ZiggyImapRenderer​(ZiggyFeatureRenderer renderer,
                                 ImageMap imageMap,
                                 URLFactory urlFactory)
        Creates a new ZiggyImapRenderer.
        Parameters:
        renderer - a ZiggyFeatureRenderer.
        imageMap - an ImageMap.
        urlFactory - an URLFactory which should be capable of creating a suitable URL from each Feature on the Sequence to be rendered.

      • getImageMap

        public ImageMap getImageMap()
        getImageMap returns the current image map.
        Returns:
        an ImageMap.
      • setImageMap

        public void setImageMap​(ImageMap imageMap)
        setImageMap sets the current image map.
        Parameters:
        imageMap - an ImageMap.
      • renderImageMap

        public void renderImageMap​(java.awt.Graphics2D g2,
                                   Feature f,
                                   SequenceRenderContext context)

        renderImageMap writes a set of image map coordinates corresponding to the rectangle sections drawn by the renderer. All the block regions of the image receive the same URL. The hotspots created by this method have the rendered Feature set as their user object.

        This method is called by renderFeature when a raster image is rendered.

        Specified by:
        renderImageMap in interface ImageMapRenderer
        Parameters:
        g2 - a Graphics2D.
        f - a Feature.
        context - a SequenceRenderContext.
