## Example ##

|
|
|
This is a simple example on how to create a QR-Code and write it to a png-file
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"image/png"
|
|
"os"
|
|
|
|
"github.com/boombuler/barcode"
|
|
"github.com/boombuler/barcode/qr"
|
|
)
|
|
|
|
func main() {
|
|
// Create the barcode
|
|
qrCode, _ := qr.Encode("Hello World", qr.M, qr.Auto)
|
|
|
|
// Scale the barcode to 200x200 pixels
|
|
qrCode, _ = barcode.Scale(qrCode, 200, 200)
|
|
|
|
// create the output file
|
|
file, _ := os.Create("qrcode.png")
|
|
defer file.Close()
|
|
|
|
// encode the barcode as png
|
|
png.Encode(file, qrCode)
|
|
}
|
|
```
