The text rollup annotation object extends AnnNoteObject by adding an Expanded property. When this property is set to false, the text rollup object looks and behaves like a normal note. When Expanded is set to false, the text rollup object will shrink to show only one line of text. This saves space on the container surface. For more information, refer to Using Text in Annotation Object. For more information about the text rollup annotation object refer to AnnTextRollupObject. For more information about the automated text rollup annotation object, refer to Annotation Objects - Automated Features.
