ID2D1DeviceContext1::CreateStrokedGeometryRealization method (d2d1_2.h)
Creates a device-dependent representation of the stroke of a geometry that can be subsequently rendered.
Syntax
HRESULT CreateStrokedGeometryRealization(
[in] ID2D1Geometry *geometry,
FLOAT flatteningTolerance,
FLOAT strokeWidth,
[in, optional] ID2D1StrokeStyle *strokeStyle,
[out] ID2D1GeometryRealization **geometryRealization
);
Parameters
[in] geometry
Type: ID2D1Geometry*
The geometry to realize.
flatteningTolerance
Type: FLOAT
The flattening tolerance to use when converting Beziers to line segments. This parameter shares the same units as the coordinates of the geometry.
strokeWidth
Type: FLOAT
The width of the stroke. This parameter shares the same units as the coordinates of the geometry.
[in, optional] strokeStyle
Type: ID2D1StrokeStyle*
The stroke style (optional).
[out] geometryRealization
Type: ID2D1GeometryRealization**
When this method returns, contains the address of a pointer to a new geometry realization object.
Return value
Type: HRESULT
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| HRESULT | Description |
|---|---|
| S_OK | No error occurred. |
| E_OUTOFMEMORY | Direct2D could not allocate sufficient memory to complete the call. |
| E_INVALIDARG | An invalid value was passed to the method. |
Remarks
This method is used in conjunction with ID2D1DeviceContext1::DrawGeometryRealization. The D2D1::ComputeFlatteningTolerance helper API may be used to determine the proper flattening tolerance.
If the provided stroke style specifies a stroke transform type other than D2D1_STROKE_TRANSFORM_TYPE_NORMAL, then the stroke will be realized assuming the identity transform and a DPI of 96.
