Annotation Appearances

 

Annotations may contain properties that describe their appearance — such as annotation color or shape. However, these don’t guarantee that the annotation will be displayed the same in different PDF viewers. To solve this problem, each annotation can define an appearance stream that should be used for rendering the annotation.

 

When you modify the annotation properties, you must call the UpdateAp() method in the CPDFAnnotation class.
