Index of the zone in the zone list from which the information is requested. |
| lplpRects |
LPAT_RECT* |
Pointer to an array of AT_RECT structures for storing the requested shape information. Can't be NULL. After evaluating the result, the application should call IG_REC_free to free this array. |
| lpRectCount |
LPAT_INT |
Pointer to a number variable for storing the number of rectangles in the lplpRects array. Can't be NULL. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
