type Decoder struct {
	// contains filtered or unexported fields
}

func NewDecoder

func NewDecoder(options ...func(*Decoder) error) (*Decoder, error)

func (*Decoder) Decode

func (d *Decoder) Decode(filename string, format imagemeta.ImageFormat, r io.Reader) (ex *ExifInfo, err error)

Filename is only used for logging.

type ExifInfo

type ExifInfo struct {
	// GPS latitude in degrees.
	Lat float64

	// GPS longitude in degrees.
	Long float64
