# gozxing A Barcode Scanning/Encoding Library for Go
[](https://github.com/makiuchi-d/gozxing/actions/workflows/main.yml)
[](https://codecov.io/gh/makiuchi-d/gozxing)
[ZXing](https://github.com/zxing/zxing) is an open-source, multi-format 1D/2D barcode image processing library for Java.
This project is a port of ZXing core library to pure Go.

## Usage Examples
### Scanning QR code
```Go
package main
import (
"fmt"
"image"
_ "image/jpeg"
"os"
"github.com/makiuchi-d/gozxing"
"github.com/makiuchi-d/gozxing/qrcode"
)
func main() {
// open and decode image file
file, _ := os.Open("qrcode.jpg")
img, _, _ := image.Decode(file)
// prepare BinaryBitmap
bmp, _ := gozxing.NewBinaryBitmapFromImage(img)
// decode image
qrReader := qrcode.NewQRCodeReader()
result, _ := qrReader.Decode(bmp, nil)
fmt.Println(result)
}
```
### Generating CODE128 barcode
```Go
package main
import (
"image/png"
"os"
"github.com/makiuchi-d/gozxing"
"github.com/makiuchi-d/gozxing/oned"
)
func main() {
// Generate a barcode image (*BitMatrix)
enc := oned.NewCode128Writer()
img, _ := enc.Encode("Hello, Gophers!", gozxing.BarcodeFormat_CODE_128, 250, 50, nil)
file, _ := os.Create("barcode.png")
defer file.Close()
// *BitMatrix implements the image.Image interface,
// so it is able to be passed to png.Encode directly.
_ = png.Encode(file, img)
}
```
