ID2D1Geometry::ComputeArea methods
Computes the area of the geometry.
Overload list
| Method | Description |
|---|---|
| ComputeArea(D2D1_MATRIX_3X2_F&,FLOAT*) | Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the default tolerance. |
| ComputeArea(D2D1_MATRIX_3X2_F*,FLOAT*) | Computes the area of the geometry after it has been transformed by the specified matrix and flattened by using the default tolerance. |
| ComputeArea(D2D1_MATRIX_3X2_F&,FLOAT,FLOAT*) | Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance. |
| ComputeArea(D2D1_MATRIX_3X2_F*,FLOAT,FLOAT*) | Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance. |
Examples
The following code example uses ComputeArea to compute the area of a specified circle (m_pCircleGeometry1).
float area;
// Compute the area of circle1
hr = m_pCircleGeometry1->ComputeArea(
D2D1::IdentityMatrix(),
&area
);
