CustomLineCap.SetStrokeCaps(LineCap, LineCap) メソッド

定義

直線の開始と終了に使用する、このカスタム キャップを構成するキャップを設定します。

public:
 void SetStrokeCaps(System::Drawing::Drawing2D::LineCap startCap, System::Drawing::Drawing2D::LineCap endCap);
public void SetStrokeCaps (System.Drawing.Drawing2D.LineCap startCap, System.Drawing.Drawing2D.LineCap endCap);
member this.SetStrokeCaps : System.Drawing.Drawing2D.LineCap * System.Drawing.Drawing2D.LineCap -> unit
Public Sub SetStrokeCaps (startCap As LineCap, endCap As LineCap)

パラメーター

startCap
LineCap

このキャップ内で直線の開始点で使用される LineCap 列挙体。

endCap
LineCap

このキャップ内で直線の終了点に使用される LineCap 列挙体。

SetStrokeCaps メソッドの使用方法を次の例に示します。 この例を実行するには、コードを Windows フォームに貼り付けます。 フォームのイベントを処理し、フォームのPaintイベント処理メソッドから を呼び出しDrawCaps、 を としてPaintEventArgs渡しますePaint

    // Construct the hook-shaped end cap.
    CustomLineCap HookCap = new CustomLineCap(null, hPath);

    // Set the start cap and end cap of the HookCap to be rounded.
    HookCap.SetStrokeCaps(LineCap.Round, LineCap.Round);

    // Create a pen and set end custom start and end
    // caps to the hook cap.
    Pen customCapPen = new Pen(Color.Black, 5);
