type IFDEntry ¶
An IFDEntry is a single entry in an Image File Directory. A value of type DataTypeRational is composed of two 32-bit values, thus data contains two uints (numerator and denominator) for a single number.

func (SortByTagInterface) Len ¶
func (s SortByTagInterface) Len() int
func (SortByTagInterface) Less ¶
func (s SortByTagInterface) Less(i, j int) bool
func (SortByTagInterface) Swap ¶
func (s SortByTagInterface) Swap(i, j int)
