Handle to the OCR document
Index of the page from which to get the zone information. This is a zero-based index.
Index of the zone for which to get the information. This is a zero-based index.
Pointer to a ZONEDATA2 structure that will be updated with zone information.
Size in bytes, of the structure pointed to by pZoneData, use sizeof(ZONEDATA2) to calculate this value.
