示例1: InsertPointIntoPolylineAfter
internal static PolylinePoint InsertPointIntoPolylineAfter(Polyline borderPolyline, PolylinePoint insertAfter,
Point pointToInsert) {
PolylinePoint np;
if (insertAfter.Next != null) {
np = new PolylinePoint(pointToInsert) { Prev = insertAfter, Next = insertAfter.Next, Polyline = borderPolyline };
insertAfter.Next.Prev = np;
insertAfter.Next = np;
} else {
np = new PolylinePoint(pointToInsert) { Prev = insertAfter, Polyline = borderPolyline };
insertAfter.Next = np;
borderPolyline.EndPoint = np;
}
Debug.Assert(
!(ApproximateComparer.Close(np.Point, np.PrevOnPolyline.Point) ||
ApproximateComparer.Close(np.Point, np.NextOnPolyline.Point)));
borderPolyline.RequireInit();
return np;
}示例2: RoundVertices
internal static void RoundVertices(Polyline polyline) {
// Following creation of the padded border, round off the vertices for consistency
// in later operations (intersections and event ordering).
PolylinePoint ppt = polyline.StartPoint;
do {
ppt.Point = ApproximateComparer.Round(ppt.Point);
ppt = ppt.NextOnPolyline;
} while (ppt != polyline.StartPoint);
RemoveCloseAndCollinearVerticesInPlace(polyline);
// We've modified the points so the BoundingBox may have changed; force it to be recalculated.
polyline.RequireInit();
// Verify that the polyline is still clockwise.
Debug.Assert(polyline.IsClockwise(), "Polyline is not clockwise after RoundVertices");
