Returns the convex hull of the given geometry. The convex hull of a single point is the point itself, the convex hull of collinear points is a line, and the convex hull of everything else is a polygon. Note that a degenerate polygon with all vertices on the same line will result in a line segment.

Rectangle.convexHull(maxError, proj)Geometry
this: geometryGeometry

Calculates the convex hull of this geometry.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, default: null

The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.

// Define a Rectangle object.

// Apply the convexHull method to the Rectangle object.
var rectangleConvexHull = rectangle.convexHull({'maxError': 1});

// Print the result to the console.

// Display relevant geometries on the map.
