The following shows a C# example that returns a LegacyText object.
public static LegacyText buildLegacyText()
{
LegacyText legacyText = new LegacyText();
Envelope envelope = buildEnvelope();
legacyText.Rectangle = envelope;
legacyText.Text = "This is Legacy Text";
legacyText.srsName = "EPSG:4326";
Angle angle = new Angle();
angle.Value = 90;
angle.uom = AngularUnit.Degree;
legacyText.Angle = angle;
return legacyText;
}
