The StrokeCollectionConverter converts a StrokeCollection to a string that represents the StrokeCollection in base-64, encoded Ink Serialized Format (ISF). It is useful to store ink data as base-64, encoded ISF when it is not possible to store raw byte data, such as in Web pages.
The following example demonstrates how to convert a base-64, encoded ISF string to a StrokeCollection. This assumes that there is an InkPresenter called presenter.
// The base-64 encoded string that contains ink data
// in ink serialized format (ISF).
