ID2D1Geometry::GetWidenedBounds(FLOAT,ID2D1StrokeStyle*,constD2D1_MATRIX_3X2_F&,FLOAT,D2D1_RECT_F*) method (d2d1.h)
Gets the bounds of the geometry after it has been widened by the specified stroke width and style and transformed by the specified matrix.
Syntax
HRESULT GetWidenedBounds(
FLOAT strokeWidth,
[in, optional] ID2D1StrokeStyle *strokeStyle,
[ref] const D2D1_MATRIX_3X2_F & worldTransform,
FLOAT flatteningTolerance,
[out] D2D1_RECT_F *bounds
);
Parameters
strokeWidth
Type: FLOAT
The amount by which to widen the geometry by stroking its outline.
[in, optional] strokeStyle
Type: ID2D1StrokeStyle*
The style of the stroke that widens the geometry.
[ref] worldTransform
Type: const D2D1_MATRIX_3X2_F
A transform to apply to the geometry after the geometry is transformed and after the geometry has been stroked.
flatteningTolerance
Type: 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.
[out] bounds
Type: D2D1_RECT_F*
When this method returns, contains the bounds of the widened geometry. 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.
