Think about all the methods we would need to accomplish this. The first thing that comes to mind is a function that will process the command-line arguments mentioned earlier. Next, we need to write code that can add a watermark image to the main image. Let's call this
addWaterMark(). On similar lines, we will need methods that add text and date stamp to the image. We will call this
