How to slice & reverse camera view?

I am working on an app that will show reverse view from camera. For example, if current view from camera is like: ,

the app should reverse view like:

so user will see constantly reverse view from camera through this app.

I am not very sure how to achieve this. Any help or idea would be highly appreciated. Thanks!

Answer 1

I understand from your answer that you want to display the reversed view in real-time.

I would create a custom SurfaceView and override the onDraw method to split the image in two and reverse the two slices.

Then I would pass the holder of your surface to the camera object like this:

camera.setPreviewDisplay(myCustomSurfaceView.getHolder());
