Constructor Detail

BasicImapRenderer

public BasicImapRenderer(BasicFeatureRenderer renderer,
                         ImageMap imageMap,
                         URLFactory urlFactory)

Creates a new BasicImapRenderer.

Parameters:

renderer - a BasicFeatureRenderer.

imageMap - an ImageMap.

urlFactory - an URLFactory which should be capable of creating a suitable URL from each Feature on the Sequence to be rendered.

Method Detail

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(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.

renderFeature

public void renderFeature(Graphics2D g2,
                          Feature f,
                          SequenceRenderContext context)

Specified by:

renderFeature in interface FeatureRenderer

getDepth

public double getDepth(SequenceRenderContext context)

Specified by:

getDepth in interface FeatureRenderer

processMouseEvent

public FeatureHolder processMouseEvent(FeatureHolder holder,
                                       SequenceRenderContext context,
                                       MouseEvent mEvent)

Specified by:
