)

パラメータ

worldTransform: The transform to apply to the geometry outline, or NULL.
flatteningTolerance: The maximum bounds on the distance between points in the polygonal approximation of the geometry. Smaller values produce more accurate results but cause slower execution.
geometrySink: The SimplifiedGeometrySinkto which the geometry's transformed outline is appended.

戻り値の型

If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

解説

The {{Outline}} method allows the caller to produce a geometry with an equivalent fill to the input geometry, with the following additional properties: The output geometry contains no transverse intersections; that is, segments may touch, but they never cross.The outermost figures in the output geometry are all oriented counterclockwise. The output geometry is fill-mode invariant; that is, the fill of the geometry does not depend on the choice of the fill mode. For more information about the fill mode, see FillMode.Additionally, the {{Outline}} method can be useful in removing redundant portions of said geometries to simplify complex geometries. It can also be useful in combination with GeometryGroupto create unions among several geometries simultaneously.
