The ImageFormatConverter converts to and from known image formats, as specified in the ImageFormat class.
The most common type conversion is to and from a string type. The default implementation calls the ToString method of the object if the object is valid and if the destination type is string. If this method cannot convert the specified object to the specified destination type, it throws a NotSupportedException exception.
