QRGen, a small wrapper on top of ZXING for generating QRCodes in java

A couple of months ago I was looking at creating QR codes in java, and found ZXING, which is pretty awesome, you should check it out.

For convenience I made a simple wrapper API on top of zxing.

To put it to use just add the dependency to your project, and you will be able to get it from maven central:

example maven pom.xml


example build.gradle:

dependencies {
  compile ("net.glxn:qrgen:1.4")

After that you can put it to use in your project:

// get QR file from text using defaults
File file = QRCode.from("Hello World").file();
// get QR stream from text using defaults
ByteArrayOutputStream stream = QRCode.from("Hello World").stream();

// override the image type to be JPG
QRCode.from("Hello World").to(ImageType.JPG).file();
QRCode.from("Hello World").to(ImageType.JPG).stream();

// override image size to be 250x250
QRCode.from("Hello World").withSize(250, 250).file();
QRCode.from("Hello World").withSize(250, 250).stream();

// override size and image type
QRCode.from("Hello World").to(ImageType.GIF).withSize(250, 250).file();
QRCode.from("Hello World").to(ImageType.GIF).withSize(250, 250).stream();

// supply own outputstream
QRCode.from("Hello World").to(ImageType.PNG).writeTo(outputStream);

See the github page for more info: http://kenglxn.github.io/QRGen/

If you’d rather use ZXING directly, you will be able to since it is a transitive dependency of QRGen, but you could also just add the ZXING repository definition and dependency to your project:
