EXIF orientation correct replacement for golang's image.Decode
License: MIT License
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)Special thanks to Macilias: part of code is taken from his repo
Would you mind adding a license soni can use your library?

Hi. I just ran the code through the 8 jpeg images of the letter F from this blogpost. Case 2 and 4 are incorrect - fix below for you.
case "1":
// do nothing
case "2":
img = imaging.FlipH(img) // FIX: needs to be FlipH not FlipV
case "3":
img = imaging.Rotate180(img)
case "4":
img = imaging.Rotate180(imaging.FlipH(img)) // FIX: needs to be FlipH not FlipV
case "5":
img = imaging.Rotate270(imaging.FlipV(img))
case "6":
img = imaging.Rotate270(img)
case "7":
img = imaging.Rotate90(imaging.FlipV(img))
case "8":
img = imaging.Rotate90(img)
}EDIT: also I just noticed you're not handling the err returned from reader.Seek here: https://github.com/edwvee/exiffix/blob/master/decode.go#L18
