旋转矩形颜色

Question

我开始在java中构建模拟并使用矩形作为平面。但是当我旋转矩形时，它的前景颜色不会坚持下去。有人能帮助我吗？

源代码：

 private void drawTransform(Graphics g, double modifier) {

Rectangle rect = new Rectangle(130,350, 350, 15);
    AffineTransform at = new AffineTransform();
    at.rotate(-Math.toRadians(modifier), rect.getX(), rect.getY() + rect.height);

    // Transform the shape and draw it to screen
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(Color.red);
    g2d.fillRect(130, 350, 350, 15);
    g2d.draw(at.createTransformedShape(rect));

}

Answer 1

使用fill代替draw：

g2d.fill(at.createTransformedShape(rect));
