public void Widen(float strokeWidth, D2D1StrokeStyle strokeStyle, D2D1Matrix3X2F worldTransform, D2D1SimplifiedGeometrySink geometrySink)

Parameters

Type	Name	Description
float	strokeWidth	The amount by which to widen the geometry.
D2D1StrokeStyle	strokeStyle	The style of stroke to apply to the geometry.
D2D1Matrix3X2F	worldTransform	The transform to apply to the geometry after widening it.
D2D1SimplifiedGeometrySink	geometrySink	The D2D1SimplifiedGeometrySink to which the widened geometry is appended.

Widen(float, D2D1StrokeStyle, D2D1Matrix3X2F, float, D2D1SimplifiedGeometrySink)

Get the geometry and widen it as well as apply an optional pen style.

Declaration

public void Widen(float strokeWidth, D2D1StrokeStyle strokeStyle, D2D1Matrix3X2F worldTransform, float flatteningTolerance, D2D1SimplifiedGeometrySink geometrySink)

Parameters

Type	Name	Description
float	strokeWidth	The amount by which to widen the geometry.
D2D1StrokeStyle	strokeStyle	The style of stroke to apply to the geometry.
D2D1Matrix3X2F	worldTransform	The transform to apply to the geometry after widening it.
float	flatteningTolerance	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.
D2D1SimplifiedGeometrySink	geometrySink	The D2D1SimplifiedGeometrySink to which the widened geometry is appended.
