Remarks
Appearances enable the annotation to be presented visually in different ways to reflect its interactions with the user. Each appearance is a form resource: a self-contained content stream to be rendered inside the annotation rectangle.
An annotation can define as many as three separate appearances:
- The "normal" appearance is used when the annotation is not interacting with the user. This appearance is also used for printing the annotation.
- The "rollover" appearance is used when the user moves the cursor into the annotation's active area without pressing the mouse button.
- The "down" appearance is used when the mouse button is pressed or held down within the annotation's active area. Each entry may contain either a single appearance (Normal, Rollover, Down) or an appearance subdictionary (NormalStates, RolloverStates, DownStates). In the latter case, the subdictionary defines multiple appearances corresponding to different appearance states of the annotation.
