,您好我要显示的矩形在相机,使得当用户采取管理单元仅该区域的矩形内进行处理。任何想法,我该怎么办呢?和矩形尺寸可以通过沿拐角拖动来调整大小。
Hi I want to show a rectangle in camera so that when the user takes snap only the region inside the rectangle can be processed. Any idea how can I do it? And the rectangle size can be resized by dragging along the corners.
我不调用摄像头应用程序。我使用的照相机API。
I am not calling the camera application. I am using the camera API.
