IFRPageEvents Interface

This is a callback interface that is used for reporting events from the FRPage object to the listeners. This interface is implemented on the client-side. See the detailed implementation advice for your development tool in Working with Connectable Objects. Below you can find a short summary.

You need to implement the IFRPageEvents interface and "advise" object implementing the interface to the FRPage object. As the interface is derived from the IUnknown interface, the client object should also implement the IUnknown methods.

An object receiving notifications through this interface's methods may do the following inside the methods' implementation:

  • Report percentage of document analysis, recognition, and export.
  • Report recognizer tips and warnings to the user.
  • Report information about completion of the operation.

Methods

Name Description
OnPageProcessed Delivers to the client information about page processing completed.
OnProgress Delivers to the client information about approximate percentage of the current operation (analysis, recognition, and export).
OnRegionProcessed Delivers to the client information about region which is processed.
OnWarning Delivers to the client tips and warnings which occurred during processing.

Remarks

This interface does not work if the Engine object is loaded as an out-of-process server.
