CD2DGeometry::GetWidenedBounds

  • Articolo

Gets the bounds of the geometry after it has been widened by the specified stroke width and style and transformed by the specified matrix.

BOOL GetWidenedBounds(
   FLOAT strokeWidth,
   ID2D1StrokeStyle* strokeStyle,
   const D2D1_MATRIX_3X2_F& worldTransform,
   CD2DRectF& bounds,
   FLOAT flatteningTolerance = D2D1_DEFAULT_FLATTENING_TOLERANCE
) const;

Parameters

  • strokeWidth
    The amount by which to widen the geometry by stroking its outline.

  • strokeStyle
    The style of the stroke that widens the geometry.

  • worldTransform
    A transform to apply to the geometry after the geometry is transformed and after the geometry has been stroked.

  • bounds
    When this method returns, contains the bounds of the widened geometry. You must allocate storage for this parameter.

  • flatteningTolerance
    The maximum bounds on the distance between points in the polygonal approximation of the geometries. Smaller values produce more accurate results but cause slower execution.

Return Value

If the method succeeds, it returns TRUE. Otherwise, it returns FALSE.
