Remarks

Please note that not all Exif files have extensions.

Currently, this method works only with Exif files. Exif files can contain extra data stored as "FlashPix extensions". This method can be used to access this extra data. Leadtools refers to this extra data as "extensions".

You must dispose the CodecsExtensionList returned from this method when you are done using it.
