PathGeometry.GetPointAtFractionLength(Double, Point, Point) メソッド

定義

この Point の長さに対して指定した分数に基づいて、PathGeometry と接線ベクターを取得します。Gets the Point and a tangent vector on this PathGeometry at the specified fraction of its length.

public:
 void GetPointAtFractionLength(double progress, [Runtime::InteropServices::Out] System::Windows::Point % point, [Runtime::InteropServices::Out] System::Windows::Point % tangent);
public void GetPointAtFractionLength (double progress, out System.Windows.Point point, out System.Windows.Point tangent);
[System.Security.SecurityCritical]
public void GetPointAtFractionLength (double progress, out System.Windows.Point point, out System.Windows.Point tangent);
member this.GetPointAtFractionLength : double * Point * Point -> unit
[<System.Security.SecurityCritical>]
member this.GetPointAtFractionLength : double * Point * Point -> unit
Public Sub GetPointAtFractionLength (progress As Double, ByRef point As Point, ByRef tangent As Point)

パラメーター

progress
Double

この PathGeometry の長さに対する分数。The fraction of the length of this PathGeometry.

point
Point

このメソッドから制御が戻ると、PathGeometry の長さに対して指定した分数に基づく場所が格納されます。When this method returns, contains the location on this PathGeometry at the specified fraction of its length. このパラメーターは初期化せずに渡されます。This parameter is passed uninitialized.

tangent
Point

このメソッドから制御が戻ると、接線ベクターが格納されます。When this method returns, contains the tangent vector. このパラメーターは初期化せずに渡されます。This parameter is passed uninitialized.
