type Reader interface {
	GetExifBlob(image RawImageBytes) (rawExif RawExifBytes, err error)
	GetGPSInfo(exifData RawExifBytes) (*GpsInfo, error)
}

Reader parses EXIF data from and image

func NewExifReader

func NewExifReader(parsingLib ReaderType) (Reader, error)

NewExifReader creates a new instance of exif.Reader

type ReaderType

type ReaderType string

ReaderType represents the exif reader library to be used
