Parameters

Return Value

Type: System.Boolean
true if adornment was added to the layer, otherwise false.
visualSpan does not intersect the text that is visible in the view.

Remarks

If visualSpan is specified, then the adornment will be removed whenever any line that crosses visualSpan is formatted. If visualSpan has a length of zero, then it will be invalidated when the line that contains the following character is invalidated (or the last line, if the visual span is at the end of the buffer).
