解决方案

问题是你可能在客户端完全完成了这一切。



我建议使用HTML5 Canvas元素。请参阅此最低限度手册： http://www.html5canvastutorials.com/tutorials/html5-canvas-image-裁剪 [ ^ ]。



您的解决方案需要更多，但处理图像是关键。解释此类行为的所有方面需要太多时间和空间来适应快速问题和解答论坛格式。

The problem is that you probably doing it all fully on the client side.

I would advise to use HTML5 Canvas element. Please see this minimal manual: http://www.html5canvastutorials.com/tutorials/html5-canvas-image-crop[^].

Your solution will require a lot more, but handling the images is the key. Explaining all the aspects of such behavior would require too much time and space to fit this Quick Questions and Answers forum format.
