Method RotateSelectedElement

RotateSelectedElement(double, MapPoint?)

Rotates the SelectedElement by the specified angle.

Declaration

public void RotateSelectedElement(double angle, MapPoint? origin)

Parameters

Type	Name	Description
double	angle	The angle by which to rotate the selected element, counterclockwise, in degrees.
MapPoint	origin	The center of rotation. If null, the center of the extent of the SelectedElement is used.

Remarks

The angle of rotation is used in the form of the modulo of 360 degrees; for example rotating by 540 degrees is equivalent to rotating the by 180 degrees. A positive value corresponds to a counterclockwise rotation.

If the origin Point has a different SpatialReference than the associated MapView, the point will be reprojected before the geometry is rotated, using the default transformation.

Any z-value of the origin MapPoint is ignored. RotateSelectedElement(double, MapPoint?) only supports rotations in the xy-plane.

If SelectedElement is a GeometryEditorVertex, or a GeometryEditorGeometry of type Point, and the origin parameter is null (or is at the same location as the selected element), then rotating the selected element has no effect.

Exceptions

Type	Condition
InvalidOperationException	The GeometryEditor must be started and have a SelectedElement set in order to rotate an element. GeometryEditorMidVertex elements cannot be rotated.
