    ) As CIMTextSymbol

    Parameters

    symbol
    ArcGIS.Core.CIM.CIMPolygonSymbol
    size
    The size of the text symbol to construct.
    fontFamilyName
    The font family name of the text symbol to construct.
    fontStyleName

    Return Value

    Exceptions
    ExceptionDescription
    This method must be called within the lambda passed to QueuedTask.Run
    Remarks
    If the font family is null or does not exist the current default font family will be assigned. If the font style is null or does not exist, the default font style for the font family will be assigned.
