Exiffix is a one function golang library made to be a replacement for image.Decode to handle orientation stored in EXIF data.

exiffix.Decode has mostly the same signature as image.Decode. The difference is that it requires io.ReadSeeker instead of io.Seeker.

file, err := os.Open(path)
if err != nil{
  panic(err)
}
defer file.Close()
img, fmt, err := exiffix.Decode(file)
