TExifReaderUtility Class Reference

class TExifReaderUtility

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

Note: Unless otherwise stated in a method's documentation, TInt& arguments represent unsigned quantities and will be updated with unsigned values, even though TInt is a signed type. In such cases, proper typecasting should be used to ensure that the values are correctly treated as unsigned.

Note: Get method arguments will only be updated if the method is returning KErrNone.
