virtual MgGeometry* MgGeometry::ConvexHull

(

)

[virtual]

Remarks:

In section 12.4.2 [JTS1.4 ] states: "The convex hull of a Geometry is the smallest convex Polygon that contains all the points in the Geometry. If the convex hull contains fewer than 3 points, a lower dimension Geometry is returned, specified as follows:

Points in Convex Hull	Geometry of Result
0	empty GeometryCollection
1	Point
2	LineString
3 or more	Polygon

JTS will return a Geometry with the minimal number of points needed to represent the convex hull. In particular, no more than two consecutive points will be collinear."

.NET Syntax

virtual MgGeometry ConvexHull();

Java Syntax

virtual MgGeometry ConvexHull();

PHP Syntax

virtual MgGeometry ConvexHull();

Returns:

An MgGeometry that represents the convex hull of the geometric entity.
