Exiv2::Internal::TiffSubIfd Class Reference
This class models a TIFF sub-directory (sub-IFD). A sub-IFD is an entry with one or more values that are pointers to IFD structures containing an IFD. The TIFF standard defines some important tags to be sub-IFDs, including the Exif and GPS tags. More...

Detailed Description
This class models a TIFF sub-directory (sub-IFD). A sub-IFD is an entry with one or more values that are pointers to IFD structures containing an IFD. The TIFF standard defines some important tags to be sub-IFDs, including the Exif and GPS tags.The documentation for this class was generated from the following file:
