Updates the shape of the specified zone in the user zone list of the specified page.
Handle to the OCR document. This handle is obtained by calling the L_Doc2StartUp function.
Index of the page. This is a zero-based index.
Index of the zone. This is a zero-based index.
Array of rectangles to be used when setting the specified zone on the specified page.
Number of rectangle array elements being set.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
To get the rectangles for a zone call the L_Doc2GetZoneLayout / L_Doc2GetZoneLayoutExt function.
To add a user zone, call the L_Doc2AddZone / L_Doc2AddZoneExt function. To add rectangle(s) to a user zone, making its shape an irregular shape, call the L_Doc2AddZoneRect / L_Doc2AddZoneRectExt function.
