While recognizing a symbol, the recognizer may also identify critical points on the symbol called hot spots. Hot spots can apply to any symbol but usually are of interest only for gestures. For example, if the user writes an X for deletion, the cross of the X its hot spot points to the item to be deleted. If the recognizer identifies hot spots for a recognized symbol, it places coordinates for all hot spot points in the rgpntHotSpot member of the symbol's SYG structure. This array can hold up to MAXHOTSPOT points. Note that all symbols do not have the same number of hot spots, and many symbols have none.
