Zxing是Google提供的關於條碼(一維碼、二維碼)的解析工具,提供了二維碼的生成與解析的方法。
java
一、二維碼生成工具
try { String content = "http://www.oschina.net"; String path = "D:/testImage/qrcode"; String filename = "qrcode.jpg"; MultiFormatWriter multiFormatWriter = new MultiFormatWriter(); Map hints = new HashMap(); hints.put(EncodeHintType.CHARACTER_SET, "UTF-8"); BitMatrix bitMatrix = multiFormatWriter.encode(content, BarcodeFormat.QR_CODE, 400, 400,hints); File file1 = new File(path); if(!file1.exists()){ file1.mkdirs(); } file1 = new File(path,filename); MatrixToImageWriter.writeToFile(bitMatrix, "jpg", file1); } catch (Exception e) { e.printStackTrace(); }
二、二維碼解析.net
try { MultiFormatReader formatReader = new MultiFormatReader(); String filePath = "D:/testImage/qrcode/qrcode169.jpg"; File file = new File(filePath); BufferedImage image = ImageIO.read(file);; LuminanceSource source = new BufferedImageLuminanceSource(image); Binarizer binarizer = new HybridBinarizer(source); BinaryBitmap binaryBitmap = new BinaryBitmap(binarizer); Map hints = new HashMap(); hints.put(EncodeHintType.CHARACTER_SET, "UTF-8"); Result result = formatReader.decode(binaryBitmap,hints); System.out.println("result = "+ result.toString()); System.out.println("resultFormat = "+ result.getBarcodeFormat()); System.out.println("resultText = "+ result.getText()); } catch (Exception e) { e.printStackTrace(); }
