IImageDocumentEvents Interface

This is a callback interface that is used for reporting events from the ImageDocument 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.

In C++ you need to implement the IImageDocumentEvents interface, obtain a connection point, and "advise" object implementing the interface to the ImageDocument object. As the interface is derived from the IUnknown interface, the client object should also implement the IUnknown methods.

Visual Basic users that want to receive notifications from the ImageDocument object should declare it WithEvents and implement the following Sub:

Public WithEvents imageDoc As FREngine.IImageDocument
Private Sub imageDoc_TransformationMade(ByVal rotation As RotationTypeEnum, _
                                        ByVal wasMirrored As Boolean, _
                                        ByVal wasInverted As Boolean)
End Sub


Name Description
TransformationMade Called by ABBYY FineReader Engine when some transformation was made with the ImageDocument.
