function Leadtools.Annotations.Core.AnnTextHiliteObject()

AnnTextHiliteObject derives from AnnTextReviewObject and has a renderer that will fill each rectangle with the current Fill value. The constructor of this object will create a solid yellow brush and set it in Fill and sets the Opacity value to 0.5.

Text hilite is used by application such as Microsoft Word and Adobe Acrobat to mark part of the text in review mode. The LEADTOOLS Document Viewer uses text hilite for this purpose. It also stores any text notes added by the reviewer in the metadata of the AnnObject using the AnnObject.ContentMetadataKey key.

Programmatically, the boundaries and rectangles of the text hilite object can be controlled using the following properties:
