Use Composite (Watermark) to specify an image, text, or a shape to overlay or underlay your original image.
The component that is over or underneath is visible in areas that are beyond the edges of the top component or that are less than 100% opaque. A common use of an overlay image composite is to add a watermark.
If you add the IMQuery transformation to a policy, use the
im variable, and select Composite, you can use a query string to specify an image, text, or a shape to overlay or underlay your original image using this policy. See Syntax and Examples for the syntax for the query string parameter.
