   Stream stream
)

virtual void Load( 
   Stream^ stream

Once you set up the OCR engine, you can re-use these settings by saving the engine state into memory or to an XML file on disk. Later, reload these settings and use them in the same or a different instance of IOcrEngine.

The following table lists all the states loaded from the XML file. After the load operation completes, some or all of the settings below will be changed.

Part	Members
IOcrSettingManager (accessed through IOcrEngine.SettingManager	All the settings as obtained through IOcrSettingManager.GetSettingNames
IOcrLanguageManager (accessed through IOcrEngine.LanguageManager	The value of IOcrLanguageManager.GetEnabledLanguages
IOcrSpellCheckManager (accessed through IOcrEngine.SpellCheckManager	The values of IOcrSpellCheckManager.Enabled, IOcrSpellCheckManager.SpellLanguage and IOcrSpellCheckManager.UserDictionary.
IOcrDocumentManager (accessed through IOcrEngine.DocumentManager	The values of the IOcrDocumentManager.RejectionSymbol and IOcrDocumentManager.MissingSymbol.

You can save the settings to a .NET stream using Save, you can load and save the settings to a disk file using Load and Save.

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
