Dynamic Annotation adds annotation capabilities to your .NET applications, so that you can markup and draw objects onto a PDF document, such as underlining or highlighting, notes/comments and circles. The visible metadata superimposed does not change the underlying master PDF image. Supported objects include text, rectangle, line and eclipse. You can add one or more annotations to each page, and all annotations can be independently resized, moved, rotated and placed on different layers. You can also select multi annotations as a group.
