The .NET stream containing the zones to load.

Example

For an example, refer to AutoZone.

Remarks

Use this method to load the zones previously saved into a .NET stream with the SaveZones method.

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

After this method finishes, you can access the loaded zones in the Zones property.

To load and save the zones to a disk file, use LoadZones and SaveZones.

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 Zones collection manually and then save the result with SaveZones. Once the zones are saved. You can now process all similar forms in the following manner:

  • Add the form page or pages to an OCR document using the Pages collection of IOcrDocument.
  • Load the zones previously saved for each page using LoadZones.
  • Skip calling AutoZone and directly call IOcrPage.Recognize or RecognizeText. This will also speed up the recognition process considerably.
