ZXingP5

Introduction

ZXingP5 is QR Code library for Processing.
This is based on ZXing.

Usage

QRWriter

import org.enkatsu.zxingp5.*;

QRWriter writer;
PImage img;

void setup() {
  size(200, 200);
  writer = new QRWriter(this);
  writer.encode("Hello QR Code!!", 2);
  img = writer.getImage(width, height);
  println(writer);
}

void draw() {
  image(img, 0, 0, width, height);
}

QRReader

import processing.video.*;
import org.enkatsu.zxingp5.*;

Capture cam;
QRReader reader;

void setup() {
  size(320, 240);

  cam = new Capture(this, 320, 240);
  cam.start();
  reader = new QRReader(this);
}

void draw() {
  if (cam.available()) {
    cam.read();
    tint(255, 255);
    image(cam, 0, 0);
    String txt = reader.decode(cam);
    println(txt);
    PVector[] points = reader.getPoints();
    if (points != null) {
      for (PVector p : points) {
        println(p);
        ellipse(p.x, p.y, 10, 10);
      }
    }
  }
}
