- stream
- The .NET stream that will contain the zones data.

Parameters
- stream
- The .NET stream that will contain the zones data.
To save and load the zones of OCR pages, you can use one of these methods:
-
IOcrPage.SaveZones(fileName) or IOcrPage.SaveZones(stream): These methods save the zones of a particular OCR page to a single-page disk file or stream. These methods will not use the page number, and hence, the file or stream will contain zones that are not tied to any particular page and can be loaded back into any OCR page regardless of its number. To load these zones back into any OCR page, use IOcrPage.LoadZones(fileName) or IOcrPage.LoadZones(stream).
-
IOcrDocument.SaveZones(fileName) or IOcrDocument.SaveZones(stream): These methods save the zones of all the OCR pages in a document to a multi-page disk file or stream. The saved data will contain the page number of the zones. To load these zones, you can either use IOcrDocument.LoadZones(fileName) or IOcrDocument.LoadZones(stream) to load the zones from a multi-page file or stream back into a multi-page OCR document. Or IOcrPage.LoadZones(fileName, pageNumber) and IOcrPage.LoadZones(stream, pageNumber) to load any single page from a multi-page OCR document into a particular OCR page.
Note on loading zones from a multi-page zone stream: If the stream does not contain zones data with the correct page number, the engine will not load any zones for this page. After the method returns, any OCR page that did not have zones data will contain zero zones. (the IOcrPage.Zones property conatins 0 items). You can then use IOcrPage.AutoZone if required to re-zone this page.
Use IOcrDocument.LoadZones(stream) or IOcrPage.LoadZones(stream, pageNumber) to load all or one page zones saved by this method.
To load and save the zones to a disk file, use IOcrDocument.SaveZones(fileName), IOcrDocument.LoadZones(fileName) and IOcrPage.LoadZones(fileName, pageNumber).
Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
