推荐答案

首先，您将获得触摸位置，这非常简单(并且您可能已经知道该怎么做:-)).

接下来，创建一个源矩形(指定图像一部分的矩形)，并将其设置为大约手指大小(也许是64x64)的触摸位置.

最后，存储该源矩形，当用户希望查看图像时，只需显示用户按下的图像部分即可.

Hi,

You would first get the touch location, which is very simple (and you probably already know how to do :-)).

Next, create a source rectangle (a rectangle that specifies part of the image), and set it to the touch position, with about the size of a finger (maybe 64x64).

Finally, you store that source rectangle, and when the user wants to see the image, you simply show the part of the image where the user pressed.
