Recognition
About the Recognition System 9-5
Figure 9-1 Recognizers create units from input strokes
Shapes 9
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.
