How to create my first watermark?
  

On the top menu-tool bar, look for Text or Image. If you click the Text, you create a default text watermark. If you click the Image, you will be prompted to open and image. As soon as you choose a proper image, an image watermark will be created in its default position.

The watermark created will be selected by default so that you can modify its parameters with the menu-tool bar system.
