Abstract
Methods and systems for rendering watermarks in a computer system are provided. One technique renders a content unit based on a call from an application, and renders a watermark for the content based on a call from a tool separate from the application. Another technique for rendering a watermark for content displayed on a display screen renders the content via a content window on the display, and renders the watermark via another window on the display that overlays at least a portion of the content window.
