A implementation of Go binding for libwebp.
- libwebp 0.4, 0.5
The examples directory contains example codes and images.
package main
import (
"github.com/harukasan/go-libwebp/test/util"
"github.com/harukasan/go-libwebp/webp"
)
func main() {
var err error
// Read binary data
data := util.ReadFile("cosmos.webp")
// Decode
options := &webp.DecoderOptions{}
img, err := webp.DecodeRGBA(data, options)
if err != nil {
panic(err)
}
util.WritePNG(img, "encoded_cosmos.png")
}
You can set more decoding options such as cropping, flipping and scaling.
package main
import (
"bufio"
"image"
"github.com/harukasan/go-libwebp/test/util"
"github.com/harukasan/go-libwebp/webp"
)
func main() {
img := util.ReadPNG("cosmos.png")
// Create file and buffered writer
io := util.CreateFile("encoded_cosmos.webp")
w := bufio.NewWriter(io)
defer func() {
w.Flush()
io.Close()
}()
config := webp.ConfigPreset(webp.PresetDefault, 90)
// Encode into WebP
if err := webp.EncodeRGBA(w, img.(*image.RGBA), config); err != nil {
panic(err)
}
}
