示例1: main
func main() {
var buf bytes.Buffer
var width, height int
var data []byte
var err error
// Load file data
if data, err = ioutil.ReadFile("./testdata/1_webp_ll.webp"); err != nil {
log.Fatal(err)
}
// GetInfo
if width, height, _, err = webp.GetInfo(data); err != nil {
log.Fatal(err)
}
fmt.Printf("width = %d, height = %d\n", width, height)
// Decode webp
m, err := webp.Decode(bytes.NewReader(data))
if err != nil {
log.Fatal(err)
}
// Encode lossless webp
if err = webp.Encode(&buf, m, &webp.Options{Lossless: true}); err != nil {
log.Fatal(err)
}
if err = ioutil.WriteFile("output.webp", buf.Bytes(), 0666); err != nil {
log.Fatal(err)
