Remarks
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.
