## Install libwebp
#### MacOS:
```bash
brew install webp
```
#### Linux:
```bash
sudo apt-get update
sudo apt-get install libwebp-dev
```
## Install
`go get -u github.com/kolesa-team/go-webp`
## Examples
#### Decode:
```go
package main
import (
"image/jpeg"
"log"
"os"
"github.com/kolesa-team/go-webp/decoder"
"github.com/kolesa-team/go-webp/webp"
)
func main() {
file, err := os.Open("test_data/images/m4_q75.webp")
if err != nil {
log.Fatalln(err)
}
output, err := os.Create("example/output_decode.jpg")
if err != nil {
log.Fatal(err)
}
defer output.Close()
img, err := webp.Decode(file, &decoder.Options{})
if err != nil {
log.Fatalln(err)
}
if err = jpeg.Encode(output, img, &jpeg.Options{Quality:75}); err != nil {
log.Fatalln(err)
}
}
```
```bash
go run example/decode/main.go
```
#### Encode
```go
package main
import (
"github.com/kolesa-team/go-webp/encoder"
"github.com/kolesa-team/go-webp/webp"
"image/jpeg"
"log"
"os"
)
func main() {
file, err := os.Open("test_data/images/source.jpg")
if err != nil {
log.Fatalln(err)
}
img, err := jpeg.Decode(file)
if err != nil {
log.Fatalln(err)
}
output, err := os.Create("example/output_decode.webp")
if err != nil {
log.Fatal(err)
}
defer output.Close()
options, err := encoder.NewLossyEncoderOptions(encoder.PresetDefault, 75)
if err != nil {
log.Fatalln(err)
}
if err := webp.Encode(output, img, options); err != nil {
log.Fatalln(err)
}
}
```
```bash
go run example/encode/main.go
```
