Remarks
The text rollup annotation object extends AnnNoteObject by adding an IsExpanded property. When this property is set to false, the text rollup object looks and behaves like a normal note. When IsExpanded is set to false, the text rollup object will shrink to show only one line of text. This saves space on the container surface.
