Geometry Class

Abstract base class for all geometry classes.

Namespace: Carmenta.Engine
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECore assembly)

Thread safety: Members defined in this class are, in general, not thread-safe. Show

Syntax

public abstract class Geometry : EngineObject

Remarks

An instance of a Geometry class is normally used as part of a Feature. The same geometry instance cannot be shared between two different features.

Each geometry instance is expressed in the coordinate reference system (the Crs) of its Feature. But the geometry instance itself knows nothing about how the Crs is related to the world, not even the unit of coordinates, so the methods and properties of Geometry and its subclasses use the Crs as an uninterpreted coordinate system. For example, the PolygonGeometry.Area method will return an area in square degrees if the Crs uses the LongLat projection.

Geometry Members

The Geometry type has the following members.

Properties

Name	Description
IsDisposed	Gets a value that tells whether the current Geometry has been disposed. Inherited from EngineObject
IsReadOnly	Gets a value indicating whether the Geometry is read-only or not.
IsValid	Gets a value indicating whether the Geometry is valid or not.
NativeHandle	Gets the native Carmenta Engine kernel object the current Geometry represents. Inherited from EngineObject
Type	Gets the geometry type of a Geometry.

Methods

Name	Description
CalculateBounds	Returns the bounding rectangle of the Geometry.
Clone	Creates a copy of an object. Inherited from EngineObject
Dispose	Releases the reference to the native Carmenta Engine kernel instance the EngineObject represents. Inherited from EngineObject
Equals	Determines whether this instance is equal to another. Inherited from EngineObject
FromWellKnownBinary	Overloaded. Initializes a new Geometry instance from a WKB representation.
FromWellKnownText	Overloaded. Initializes a new Geometry instance from a WKT representation.
Move	Moves the Geometry by the specified offset.
ToWellKnownBinary	Converts a Geometry instance into WKB representation.
ToWellKnownText	Converts a Geometry instance into WKT representation.
Transform	Applies a 2D transform to the geometry.
