下午好，我需要帮助，我想增加正方形的大小，当我使用Angular 0和270时，它正常工作，但是当单词的Angular 是90和180时，当它用鼠标增加时，它不遵守规则，按照面板上的数据
Angular ：0

Angular 90

此处代码：

txtpn1 = new JEditorPane() {
            @Override
            protected void paintComponent(Graphics g) {
                int angle = txtpn[0];  //Angulo 0,90,180,270 
                Graphics2D g2 = (Graphics2D) g;
                g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
                AffineTransform aT = g2.getTransform();
                Shape oldshape = g2.getClip();
                double x = getWidth() / 2.0;
                double y = getHeight() / 2.0;
                aT.rotate(Math.toRadians(angle), x, y);
                g2.setTransform(aT);
                super.paintComponent(g);
            }

        txtpn1.addMouseMotionListener(new MouseMotionAdapter() {
            @Override
            public void mouseDragged(MouseEvent arg0) {
                arrastarObejto(txtpn1, arg0);
        }
    }
    public void arrastarObejto(JComponent component, MouseEvent e) {
        if (component.getCursor().getType() != 11 && component.getCursor().getType() != 9) {
            component.setLocation(component.getLocation().x + e.getX(), component.getLocation().y + e.getY());
        }

        if (component.getCursor().getType() == 11 || component.getCursor().getType() == 9) {
            component.setSize(e.getX(), e.getY()); //Here is the error
       }
   }

简单的代码，当正方形成90度时，我不能拉伸它
