ID2D1Geometry::Widen(FLOAT,ID2D1StrokeStyle*,constD2D1_MATRIX_3X2_F&,FLOAT,ID2D1SimplifiedGeometrySink*) method (d2d1.h)
Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink after it has been transformed by the specified matrix and flattened using the specified tolerance.
Syntax
HRESULT Widen(
FLOAT strokeWidth,
ID2D1StrokeStyle *strokeStyle,
const D2D1_MATRIX_3X2_F & worldTransform,
FLOAT flatteningTolerance,
ID2D1SimplifiedGeometrySink *geometrySink
);
Parameters
strokeWidth
Type: [in] FLOAT
The amount by which to widen the geometry.
strokeStyle
Type: [in, optional] ID2D1StrokeStyle*
The style of stroke to apply to the geometry, or NULL.
worldTransform
Type: [in] const D2D1_MATRIX_3X2_F &
The transform to apply to the geometry after widening it.
flatteningTolerance
Type: [in] FLOAT
The maximum error allowed when constructing a polygonal approximation of the geometry. No point in the polygonal representation will diverge from the original geometry by more than the flattening tolerance. Smaller values produce more accurate results but cause slower execution.
geometrySink
Type: [in] ID2D1SimplifiedGeometrySink*
The ID2D1SimplifiedGeometrySink to which the widened geometry is appended.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
