tiffFileFlush IFD Implementation

IFD Implementation



The tiffFileFlush function is present so that the proper modification time of the TIFF file can be set. When this function is called, it records the time so that, after the TIFF file is closed, the time stamp on the file may be updated to reflect the actual time of the last change to the file.

Without this function, any associated reduced resolution data sets are treated as out of date by the class owner because the modification time of the TIFF file will appear to be later than the creation of the reduced resolution data sets (since the TIFF file will not be closed until after the reduced resolution data sets have been computed).
