ID2D1Geometry::StrokeContainsPoint(D2D1_POINT_2F,FLOAT,ID2D1StrokeStyle*,constD2D1_MATRIX_3X2_F&,FLOAT,BOOL*) method (d2d1.h)

  • Article

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] 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.
