The default value is 0
The offset within a TIFF file where the page starts.
This serves as a reference page for loading pages from a large TIFF file.
The value of the UseImageFileDirectoryOffset must be set to true in order for the toolkit to use the ImageFileDirectoryOffset value when loading TIFF images.
Some restrictions apply to this function if you use an IFD to indicate to which page to write a comment, tag, metadata, or GeoKey. See the Loading And Saving Large TIFF/BigTIFF Files topic for more information.
