GrapeCity.Documents.Pdf.Annotations.Appearance

Appearance Class

Represents the appearance of an annotation in normal, rollover and down states.

In the simplest case the appearance can be defined by a single FormXObject specified by the Default property.

In more complex cases it can be defined as a subdictionary specified by the this[string] property. For example, an annotation representing an interactive check box might have two appearance states named On and Off.

See PDF specification for details.
