Comments

Inserts L_OcrZone at the internal zones list of the page at specified index.

If the zone index is outside the range of the internal zones list an error will return, so its a good practice to always check for zones count using L_OcrPage_GetZoneCount to determine the correct index where you wish to insert the new zone.
