BPG for Go
BPG is defined at: http://bellard.org/bpg/
Install
Install GCC or MinGW (http://tdm-gcc.tdragon.net/download) at first, and then run these commands:
1. Assure set the `CGO_ENABLED` environment variable to `1` to enable `CGO` (Default is enabled).
2. `go get github.com/chai2010/bpg`
3. `go run hello.go`
Examples
This is a simple example:
package main
import (
"bytes"
"fmt"
"image/png"
"io/ioutil"
"log"
"github.com/chai2010/bpg"
)
func main() {
var buf bytes.Buffer
var data []byte
var err error
data, err = ioutil.ReadFile("./testdata/lena512color.bpg")
if err != nil {
log.Println(err)
}
info, err := bpg.DecodeInfo(data)
if err != nil {
log.Println(err)
}
fmt.Printf("info: %v\n", info)
// Decode bpg
m, err := bpg.Decode(bytes.NewReader(data))
if err != nil {
log.Println(err)
}
// save as png
if err = png.Encode(&buf, m); err != nil {
log.Println(err)
}
if err = ioutil.WriteFile("output.png", buf.Bytes(), 0666); err != nil {
log.Println(err)
}
fmt.Println("Save as output.png")
}
