This method is implemented on the client-side. It is called by ABBYY FineReader Engine before the start of the page analysis process which has been invoked from Image Viewer by calling the MI_AnalyzeLayout command. For the ways how this command can be called see the Image Viewer Commands list. The method informs the client that an active page is going to be analyzed. With the help of this method it is possible to cancel the operation.

​
Syntax

​
C++

HRESULT OnAnalyzePage( VARIANT_BOOL* Cancel );

​
C#

void OnAnalyzePage( out bool Cancel );

​
Visual Basic .NET

Sub OnAnalyzePage(ByRef Cancel As Boolean)

​
Parameters

Cancel [out] You may set this variable to TRUE to indicate that the process should be terminated. In this case, the page will not be analyzed.

​
Return values

[C++ only] If this method returns a value other than S_OK, it indicates that an error occurred on the client-side, and in this case the value of the Cancel parameter is not taken into account.

​
Remarks

The client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
