Ink regions in an overlay control

Overlaying electronic ink over a document. In some embodiments, a developer may easily define an inking surface over a document, wherein the document may or may not be ink-compatible. The inking surface may act as an input interface such that a user may write onto the inking surface and the ink may be transferred to the document as ink data and/or recognized text. The inking surface may be overlaid upon the document or may include the document as a background feature. The inking surface may further have one or more regions that may be linked to one or more areas of the underlying document. Each region may have an associated recognizer context.
