Method ScaleSelectedElement

ScaleSelectedElement(Double, Double, MapPoint)

Scales the selected element by the specified factors.

Declaration

public void ScaleSelectedElement(double scaleX, double scaleY, MapPoint origin)

Parameters

Type	Name	Description
System.Double	scaleX	The scale factor along the x-axis. It can be positive or negative. It cannot be 0, or a non-numeric value.
System.Double	scaleY	The scale factor along the y-axis. It can be positive or negative. It cannot be 0, or a non-numeric value.
MapPoint	origin	The point relative to which the geometry will be scaled. If `null`, or IsEmpty is `true`, the center of the extent of the SelectedElement is used.

Remarks

If the origin System.Drawing.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. ScaleSelectedElement(Double, Double, MapPoint) only supports scaling the xy-dimensions.

Positive scale factors greater than 1 increase the size of the Geometry, and positive factors between 0 and 1 reduce the size of the geometry. Negative scale factors produce a geometry reflected across the axes of the origin point. Negative factors less than -1 both reflect and increase the size of the geometry, and negative factors between -1 and 0 both reflect and reduce the size of the geometry.
