    ImageGear ART can convert ART marks to PDF annotations, and PDF annotations to ART marks, giving the user the ability to edit PDF annotations using the same ImageGear ART GUI.

    ImageGear Vector and U3D Components are required and should be attached for working with PDF annotations. See Attaching Components.
