Class PointTransformation

  • All Implemented Interfaces:
    org.locationtech.jts.awt.PointTransformation
    public class PointTransformation
extends java.lang.Object
implements org.locationtech.jts.awt.PointTransformation
    Transforms a source Coordinate from a strategy to a AWT Point2D considering a canvas offset Vector2D and a viewport scale. These are supplied by a scrolling event listener through zooming and dragging actions. Furthermore, it manages the bounding box representing the visual frame of the canvas inside the mathematical vector space. This boundary is used for certain rendering purposes.
