Comments

Any symbol can have hot spots, but they are usually of interest only for gestures. For example, if the user writes "X" for deletion, the center of the "X"pics/PENAPI00090001.gifits hotspot pics/PENAPI00090001.gifpoints to the item to be deleted. Hot spots are returned in tablet coordinates. The maximum number of hot spots allowed is provided in the PENWIN.H constant MAXHOTSPOT. The Microsoft Handwriting Recognizer (GRECO.DLL), supports this function for gesture symbols only.

If cPnts is smaller than the actual number of hot spots, only cPnts points are reported.
