OnPageProcessed Method of the IFRPageEvents Interface

OnPageProcessed method of the IFRPageEvents Interface in the ABBYY FineReader Engine API — Client-side method called when an FRPage finishes processing.

This method is implemented on the client-side. It is called by ABBYY FineReader Engine for some of the methods of the FRPage object. It delivers to the client information about page processing completed.

In Windows, it can also process any system messages to help prevent applications from appearing unresponsive during long operations. This can be helpful in applications with a user interface.
