Flush Method of the FRPage Object
This method unloads and, if necessary, saves to disk the ImageDocument and the Layout objects corresponding to the FRPage object if there are no references to them. Saving to disk is an option, you can omit this stage if the data has not been changed.
The method is useful when processing documents of large sizes, in which case it decreases memory usage. After the operation on a separate document page is complete, free all references to the ImageDocument and the Layout objects corresponding to the page and call the Flush method to decrease memory usage.
Note that if you have made changes to the page and want to keep these changes, you should call Flush with the IsSaveRequired parameter set to TRUE. Otherwise, the changes can be lost when calling other methods that free memory (see Iterating Document Pages for details).
