Class PelFormat
Namespace for functions operating on Exif formats.
This class defines the constants that are to be used whenever one has to refer to the format of an Exif tag. They will be collectively denoted by the pseudo-type PelFormat throughout the documentation.
All the methods defined here are static, and they all operate on a single argument which should be one of the class constants.
