要裁剪图像，请创建一个尺寸合适的新图像，然后在其中绘制所需的部分.如果要提供UI来执行此操作，则只需让用户单击并拖动以定义一个框，即可为其绘制，然后使用其边界进行裁剪.您可能应该尝试自己做，并在遇到问题时提出一些具体问题.

To crop an image, you create a new image of the right size, and draw the section you want into it. If you want to provide UI to do that, you just have the user click and drag to define a box, which you draw for them, and then use it''s bounds to crop with. You should perhaps try to do this for yourself and ask specific questions as you get stuck.
