ComputeArea Method
ComputeArea()
Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance.
Declaration
public float ComputeArea()Returns
| Type | Description |
|---|---|
| float | When this this method returns, contains a reference to the area of the transformed, flattened version of this geometry. You must allocate storage for this parameter. |
ComputeArea(float)
Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance.
Declaration
public float ComputeArea(float flatteningTolerance)Parameters
| Type | Name | Description |
|---|---|---|
| float | flatteningTolerance | The maximum bounds on the distance between points in the polygonal approximation of the geometry. Smaller values produce more accurate results but cause slower execution. |
Returns
| Type | Description |
|---|---|
| float | When this this method returns, contains a reference to the area of the transformed, flattened version of this geometry. You must allocate storage for this parameter. |
