Method Scale
Scale(Geometry, Double, Double, MapPoint)
Scales the given geometry by the specified factors from the specified origin point.
Declaration
public static Geometry Scale(this Geometry geometry, double scaleX, double scaleY, MapPoint origin = null)
Parameters
Type | Name | Description |
---|---|---|
Geometry | geometry | The geometry to scale. |
System.Double | scaleX | The scale factor along the x-axis. It can be positive or negative. It cannot be a non-numeric value. |
System.Double | scaleY | The scale factor along the y-axis. It can be positive or negative. It cannot be a non-numeric value. |
MapPoint | origin | The point around which the geometry will be scaled. If |
Returns
Type | Description |
---|---|
Geometry | A new geometry constructed by scaling the input geometry by the specified factors from the specified origin point. |
Remarks
If the origin
has a different SpatialReference than that of the geometry
,
the point will be reprojected before the geometry is scaled, using the default transformation.
Scaling a MapPoint using the same location for the origin parameter returns a MapPoint with the same values as the input.
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. 0 or 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. Scale
factors of -1 reflect the geometry across the axes of the origin point without changing the size.
Supports true curves.
