SCENE_IMAGE_NAME

protected final String SCENE_IMAGE_NAME

Name of the image for this scene

Constructor Detail

AbstractSceneHandler

public AbstractSceneHandler(Rectangle parentBounds,
                            IDataImageLoader xmlLoader,
                            DisplayImageDIResolver resolver,
                            String imageName)

Method Detail

findPolygon

protected String findPolygon(int x,
                             int y)

Find the polygon name that contains the coordinates. It is expected that the polygons are not overlapping. Is this not the case the first found polygon name is returned.

Parameters:

x - coordinate

y - coordinate

Returns:

name of the polygon

initPolygons

protected void initPolygons(DisplayImageDIResolver resolver,
                            ImageData imgData,
                            ImageScaleState state,
                            Point offset)

Setting the positions of the polygons on the screen

getBounds

protected Rectangle getBounds()

getImage

public BufferedImage getImage()

Retrieve the image that is cached with this handler

Specified by:

getImage in interface ISceneHandler

Returns:
