Remarks

Adds updating a zone in the zone list of the specified page. After the zone is added, the zone list is recalculated automatically. When adding a zone, the application should directly initialize the following properties of the RasterDocumentZoneData class, since these members will not take their default values: The OCR engine manages the RasterDocumentZoneData.Id property, except for OMR zones using the "filled-in-error" facility. The RasterDocumentZoneData.Type property should be one of the following values: For successful zone update, the whole zone area must lie within the page area and the top left coordinates of the zone must have lower values than those of the bottom right ones. To update only the zone area, call UpdateZoneArea.
For more information, refer to Working with Zones.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
