Reshapes the target polyline or polygon. The reshaping polyline can have only one part. If the target was not reshaped, an empty geometry of the saem type is returned.

Remarks
Reshapes the target polyline or polygon. The reshaping polyline can have only one part. If the reshaper does not intersect the target polyline, or does not define a closed loop for the target polygon, then an empty geometry of the same type as the target geometry is returned. The orientation of the reshaper is not considered. The following rules for polygon and polyline reshaping are used:
Polygons:. only one ring (part) is explicitly reshaped – the first one in index order that intersects the reshaping path. The longest portion of the original ring boundary is preserved. The reshaped polygon is re-simplified after the reshape operation has been applied, so the rules for simplification will determine what happens if multiple rings interact with the reshaping path. The graphics show how preserving the longest portion of the boundary can invert the ring in some cases. If more complicated reshaping behavior is desired, a combination of auto-complete, cutting and union can be used.
Polylines: multiple paths (parts) can be affected by the reshaping path. The following graphics show three cases. The polyline being reshaped has part sequence and part orientations shown in red in the upper left graphic. The reshape is shown on the left of each row. The result is shown on the right of each row.
