Hi Guys
The problem affects 24.9 and 24.10
We are observing a significant slow down to the processing of the attached file using the above versions. The problem is not present in 24.8

The issue occurs in with the following code during the flattening process

Using Doc As New Document(pSourceFile)

        For Each p As Page In Doc.Pages
            For Each an As Annotation In p.Annotations
                an.Flatten()
            Next
        Next
    End If

    If pDestination.Length > 0 Then
        Doc.Save(pDestination)
    Else
        Doc.Save(pSourceFile)
    End If
End Using

Catch ex As Exception
Return False
Finally

The issue has been reproduced, the performance regression is quite significant.
I will create a task for the development team.
Thanks for writing to us.

As a workaround, I can suggest using the Flatten() method on the Page object (instead of calling it separately for each annotation) - this works just as fast.
