About the Recognition System

Recognizers create units from input strokes
Shapes

When the recognition system returns a shape unit to the view, the shape is displayed
as the
clPolygonView
child view of a
clEditView
view. The shape unit contains
a single, cleaned-up version of the original strokes. The shape recognizer may
make the original shape more symmetrical, straighten its curves, or close the shape.
There is no developer interface to shape recognition. To manipulate shapes
returned by the recognition system, you must extract polygon view children from
edit views yourself. You can do so from within an optional
ViewAddChildScript
method that you supply. The system invokes this method
for each
clPolygonView
or
clParagraphView
child added to an edit view.
