TExifWriterUtility in Multimedia ICL

class TExifWriterUtility;

Description

This class offers a friendly interface to write the metadata in exif encoded image files

Note: Unless otherwise stated in a method's documentation, it should be assumed that TInt arguments are representing unsigned quantities, even though TInt is a signed type. So unless otherwise stated, these parameters should be given unsigned values only.
