I wanna使用“Path2D”类制造了一种铅。 我的问题是,在每一交汇点打上我们可以看到的灯塔的时候(见所附图像)。

https://i.stack.imgur.com/RSuID.png

我的法典如下:

public void mouseDragged( MouseEvent e ) {
    path2D.reset();
    path2D.moveTo(last_x, last_y);
    path2D.lineTo( mouse_x, mouse_y );

    BasicStroke bs = new BasicStroke( 10, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND );

    // g is a Graphic2D object
    g.setStroke( bs );
    g.setColor( new Color( 0.0f, 0.0f, 0.0f, 0.3f) );
    g.draw( path2D );

    repaint()
}

我的理解是,它产生于透明度和并非一条途径。 仅举一个“开拓者”的例子,但每次重新铺开这条路,透明度消失。

任何解决办法?

提前感谢!

这里的答案是使用三重缓冲技术。
