GoHeif - A go gettable decoder/converter for HEIC based on libde265
Intel and ARM supported
Install
go get git.sequentialread.com/forest/goheif
- Code Sample
func main() {
flag.Parse()
...
fin, fout := flag.Arg(0), flag.Arg(1)
fi, err := os.Open(fin)
if err != nil {
log.Fatal(err)
}
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 {
log.Fatalf("Failed to create output file %s: %v\n", fout, err)
}
defer fo.Close()
w, _ := newWriterExif(fo, exif)
err = jpeg.Encode(w, img, nil)
if err != nil {
log.Fatalf("Failed to encode %s: %v\n", fout, err)
}
log.Printf("Convert %s to %s successfully\n", fin, fout)
