IProcessingEvents Interface
This is a callback interface that is used by the InjectTextLayer method of the Engine object to report events during processing. This interface is implemented on the client-side.
An object receiving notifications through this interface's methods may do the following inside the methods' implementation:
- Process any system messages, which is useful in applications having User Interface, to avoid the effect that the application "is not responding" during long operations.
- Report percentage of document analysis, recognition, and export.
- Report recognizer tips and warnings to the user.
- Report information about completion of the operation.
