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, circles, and etc. And these visible metadata superimposed do 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.
