本文介绍了转换Rectangle2D java的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试通过特定的theta旋转Rectangle2D对象。但是我不能这样做，因为Rectangle2D的方法转换（AffineTransform）是未定义的。有关如何做到这一点的任何想法？谢谢。
I am trying to rotate a Rectangle2D object by a particular theta. But I cannot do this because the method transform(AffineTransform) is undefined for Rectangle2D. Any thoughts on how to do this? Thanks.
Rectangle2D.Double currentVehic = new Rectangle2D.Double(bottomLeft[0], bottomLeft[1],vehicWidth, vehicHeight);
// Rotate the vehicle perimeter about its center
AffineTransform rotate = new AffineTransform();
//Rectangle2D rotatedVehic = AffineTransform.getRotateInstance(theta,x,y);
rotate.setToRotation(theta, x, y);
currentVehic.transform(rotate);
return currentVehic;
推荐答案
因为 Rectangle2D 是 Shape ，您可能正在寻找 AffineTransform 方法。 引用了一个完整的示例。
Because a Rectangle2D is a Shape, you may be looking for the AffineTransform method createTransformedShape(). A complete example is cited here.
