Property IsExact
IsExact
Gets a value indicating whether the rectangle covers exactly the matched characters rather than the whole run that contains them.
public bool IsExact { get; }Property Value
Remarks
False when the run's drawn text and the part of the value it came from are not the same length, which happens when the value holds a carriage return the layout dropped: the per-character positions are then positions in the drawn text and cannot be indexed by an offset into the value, so the whole run is given instead of a wrong sub-rectangle.
