public interface IScalableImagePart

extends org.eclipse.gef.GraphicalEditPart

announces that this GEF edit part can hold scaleable data (such as zoomable images) where the children GEF editparts must be repositioned whenever the scale of this part is changed. The methods here support the mapping of coordinates and sizes between an absolute size and a current scaled size -- where the provided coordinates might be (for an image) the position relative to the actual width/height of the image, and the scaled co-ordinates need to be adjusted for the current presented size of the image.
