Example

This example creates a new text rollup object.

Visual BasicCopy Code
Private Sub AnnTextRollupObject_AnnTextRollupObject(ByVal viewer As RasterImageViewer, ByVal container As AnnContainer)
   Dim textRollup As AnnTextRollupObject = New AnnTextRollupObject()
   textRollup.Text = "My TextRollup object"
   textRollup.Font = New AnnFont("Arial", New AnnLength(10, AnnUnit.Point), FontStyle.Regular)
   textRollup.EdgeMargin = AnnLength.Empty
   textRollup.ShadowBorderWidth = New AnnLength(6, AnnUnit.Pixel)
   textRollup.Alignment = StringAlignment.Center
   textRollup.LineAlignment = StringAlignment.Center
   textRollup.Bounds = New AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel)
   container.Objects.Add(textRollup)
   textRollup.Expanded = False
   viewer.Invalidate(textRollup.InvalidRectangle)
   MessageBox.Show("Not expanded")

   textRollup.Expanded = True
   viewer.Invalidate(textRollup.InvalidRectangle)
   MessageBox.Show("expanded")
End Sub
C#Copy Code
private void AnnTextRollupObject_AnnTextRollupObject(RasterImageViewer viewer, AnnContainer container)
{
   AnnTextRollupObject textRollup = new AnnTextRollupObject();
   textRollup.Text = "My TextRollup object";
   textRollup.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular);
   textRollup.EdgeMargin = AnnLength.Empty;
   textRollup.ShadowBorderWidth = new AnnLength(6, AnnUnit.Pixel);
   textRollup.Alignment = StringAlignment.Center;
   textRollup.LineAlignment = StringAlignment.Center;
   textRollup.Bounds = new AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel);
   container.Objects.Add(textRollup);
   textRollup.Expanded = false;
   viewer.Invalidate(textRollup.InvalidRectangle);
   MessageBox.Show("Not expanded");

   textRollup.Expanded = true;
   viewer.Invalidate(textRollup.InvalidRectangle);
   MessageBox.Show("expanded");
}

Remarks

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.
