太い線で変換できない

Question

インタフェースjava.awt.geom.Shapeの実装を作成しました。これには、ANDゲートの形状を描画するPathIteratorの観点からの一連のパスが含まれます。 これでマウスポインタを動かすときにこの図形を動かしたいと思います。これは優れた動作しますが、私は線の太さを増やしたいとき、これは動作を停止します。私はペンの厚さを変えないとうまくいきます。 ペンの幅を1に設定すると機能します。しかし、私が10に設定すると、ゲートの一部だけがポイント（0,0）から引っ張られて、変換されても影響を受けません。ここ は、ゲート・ソースです：

Answer 1

次を使用します - 詳細はのGraphics2Dをお読みください。

g2d.setStroke(stroke); 
    g2d.transform(trans); 
    Shape shape2 = stroke.createStrokedShape(shape); 
    g2d.draw(shape2); 

良い仕事！
