Load zones from a multipage zones .NET stream.

public void LoadZones( 
   Stream stream 
Overloads Sub LoadZones( _ 
   ByVal stream As Stream _ 
- (void)loadZonesFromStream:(LTLeadStream *)stream error:(NSError **)error 
void LoadZones(  
   Stream^ stream 


The .NET stream containing the zones to load.


To save and load the zones of OCR pages, you can use one of these methods:

Note on loading zones from a multipage 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 contains 0 items). You can then use IOcrPage.AutoZone if required to re-zone this page.

Use this method to load the zones previously saved into a multipage zones stream file with the IOcrDocument.SaveZones(stream) method.

The zones of this page will first be cleared prior to loading the new items.

To load and save the zones to a disk file, use IOcrDocument.SaveZones(fileName), IOcrDocument.LoadZones(fileName) and IOcrPage.LoadZones(fileName, pageNumber).

Saving zones to an external file or a stream could be useful when you are processing forms. For example, you can load one of the forms and automatically find the zones inside it using AutoZone, if the automatic zone detection was not 100 percent satisfactory, you can update the zones in the IOcrPage.Zones collection manually and then save the result with IOcrDocument.SaveZones(fileName). Once the zones are saved. You can now process all similar forms in the following manner:


For an example, refer to IOcrDocument.SaveZones(fileName).
