Class GeometryStretcherView

  • public class GeometryStretcherView
extends java.lang.Object

    • Field Detail

      • MAX_VERTICES_IN_MASK

        private static final int MAX_VERTICES_IN_MASK
        The maximum number of vertices which can be shown. This is chosen to ensure reasonable performance for rendering.

        Constant Field Values

      • NEARNESS_TOL_IN_VIEW

        public static final double NEARNESS_TOL_IN_VIEW
        The nearness tolerance in view pixels. This is chosen to be as large as possible (which minimizes change to geometries) but small enough that points which appear to be coincident on the screen at a given zoom level will be magnified.
