# 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:

```Go

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")

}

```
