Methods

Difference(Geometry, Geometry)

Computes a Geometry representing the closure of the point-set of the points contained in this Geometry that are not contained in the other Geometry.

Declaration

public virtual Geometry Difference(Geometry a, Geometry b)

Parameters

Type	Name	Description
Geometry	a	The 1st Geometry
Geometry	b	The 2nd Geometry

Returns

Type	Description
Geometry	A Geometry representing the point-set difference of Geometry's a and b.

Difference(Geometry)

Intersection(Geometry, Geometry)

Computes a Geometry representing the point-set which is common to both a and b Geometry.

Declaration

public virtual Geometry Intersection(Geometry a, Geometry b)

Parameters

Type	Name	Description
Geometry	a	The 1st Geometry
Geometry	b	The 2nd Geometry

Returns

Type	Description
Geometry	A geometry representing the point-set common to the two Geometrys.
