fin, fout := flag.Arg(0), flag.Arg(1)
fi, err := os.Open(fin)
if err != nil {

}
defer fi.Close()
exif, err := goheif.ExtractExif(fi)
if err != nil {
log.Printf("Warning: no EXIF from %s: %v\n", fin, err)
}
img, err := goheif.Decode(fi)
if err != nil {
log.Fatalf("Failed to parse %s: %v\n", fin, err)
}
fo, err := os.OpenFile(fout, os.O_RDWR|os.O_CREATE, 0644)
if err != nil {
