如何只在Android中自定义相机边框拍摄图像 [英] How to take images only within the bounding box in android custom camera

问题描述

最近，我发现了一个应用程序，像下面的图片框内仅捕获图像。我应该使用SurfaceView？还是有一些其他的技术来做到这一点？我做了一个相机应用与surfaceview和思考实施蓝框像下面这样我就可以在2个蓝色箱子内所拍摄的图像图像。

Recently, I found a app that captures only the images within the boxes like the image below. Should I use a SurfaceView ? or are there some other technique to do this ? I made a camera app with surfaceview and thinking about implementing a blue box like the image below so that I can take the images within the 2 blue boxes.

推荐答案

您可以捕捉整个图像，但拍摄后仅裁剪目标区域。 ：）

You can captures the whole image, but just crop the target area after capturing. :)
