While calling processFields method, we need to send a settings with left, right, top, bottom coordinates. In my scenario, user would take an image from camera, so image might have different resolutions, may be landscaped or portrait mode. In such cases, the left, right, top, bottom differs accordingly depending upon image, so these values could not be hard coded. How do we detect boundary for an image and hence create a settings with co-ordinates dynamically and call the method processFields.
Thanks in advance for your answer.
