extends java.lang.Object

Author:

Mario De Weerd Reading and writing the relevant EXIF data should not be too complicated. Strategy is to read the header and the EXIF data. Reading first 64kB + SOI size bytes is sufficient. EXIF data must be stored in a manner that allows reconstruction later. Writing Exif data consists in replacing the APP1 Block and updating the SOI Marker.
