Annotations can have three appearance streams, which can be roughly characterised as follows: * *normal*: the only required one, and the default one; * *rollover*: used when mousing over the annotation; * *down*: used when clicking the annotation. These are given as references to form XObjects. .. note:: This class only covers the simple case of an appearance dictionary for an annotation with only one appearance state.
