Update Method of the FRPage Object
This method transfers changes in the page layout made via FineReader Engine API to Visual Components and saves these changes to the undo stack. This method should be called if the page layout has been changed via API, in order that the changes can be displayed correctly in Visual Components and can be undone if necessary.
When you call this method, the logical structure of the corresponding document becomes invalid. It is necessary to restore the document structure by calling one of the synthesis methods. However, you do not need to perform synthesis for the whole document, it is only necessary to synthesize changed pages, e.g., using the IFRPage::Synthesize method.
