ID2D1Geometry::StrokeContainsPoint(D2D1_POINT_2F,FLOAT,ID2D1StrokeStyle*,constD2D1_MATRIX_3X2_F*,FLOAT,BOOL*) method (d2d1.h)
Determines whether the geometry's stroke contains the specified point given the specified stroke thickness, style, and transform.
Syntax
HRESULT StrokeContainsPoint(
D2D1_POINT_2F point,
FLOAT strokeWidth,
ID2D1StrokeStyle *strokeStyle,
const D2D1_MATRIX_3X2_F *worldTransform,
FLOAT flatteningTolerance,
BOOL *contains
);
Parameters
point
Type: [in] D2D1_POINT_2F
The point to test for containment.
strokeWidth
Type: [in] FLOAT
The thickness of the stroke to apply.
strokeStyle
Type: [in, optional] ID2D1StrokeStyle*
The style of stroke to apply.
worldTransform
Type: [in, optional] const D2D1_MATRIX_3X2_F*
The transform to apply to the stroked geometry.
flatteningTolerance
Type: [in] FLOAT
The numeric accuracy with which the precise geometric path and path intersection is calculated. Points missing the stroke by less than the tolerance are still considered inside. Smaller values produce more accurate results but cause slower execution.
contains
Type: [out] BOOL*
When this method returns, contains a boolean value set to true if the geometry's stroke contains the specified point; otherwise, false. You must allocate storage for this parameter.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
