![]() Step 4: Below is the Mule Flow structure. Step 3: Here you also have to add Dependency in your Mule's POM file. Step2: We have to paste the java code in src/main/java in our studio with package name. Return Base64 String to Calling Function ImageString = encoder.encodeToString(imageBytes) ImageIO.write(MatrixToImageWriter.toBufferedImage(matrix), "png", bos) īase64.Encoder encoder = Base64.getEncoder() To read QR codes, well be using the JavaScript port of the Java-based. Performance has been improvement for the (byte, ) constructor and the java.lang. Scan from File: Detected QR code: Generate Download & Scan QR Code with React js. ( MatrixToImageWriter.toBufferedImage(matrix)) īyteArrayOutputStream bos = new ByteArrayOutputStream() It provides a class Base64 for encryption and decryption. String base64Image data.split (',') 1 byte imageBytes .parseBase64Binary (base64Image) BufferedImage img ImageIO.read (new ByteArrayInputStream (imageBytes)) This assumes a few things, that you know what the output file name will be and that your data comes as a string. MultiFormatWriter is a factory class that finds the appropriate Writer subclass for the BarcodeFormat requested and encodes the barcode with the supplied contents.īitMatrix matrix = new MultiFormatWriter().encode(new String(data.getBytes(charset), charset), BarcodeFormat.QR_CODE, widthOfQR, heightOfQR) the BitMatrix class represents the 2D matrix of bits Public static String generateQRcode(String data, int heightOfQR, int widthOfQR) throws WriterException, IOException Here I have used JXing java library you can use other java library that supports QR code package com.utils We will provide a string to the function that can help us to convert any string(URL/String etc) to QR code.īasic flow is like, user will call our Mule API Endpoint with query parameter and inside it will call java function that is capable of creating QR Code and will return encoded string to Mulesoft it will convert to PNG format. I am gonna talk about the solution where we can use 3rd party java library "ZXing" that can help us to create QR code. We can create our own java function by using qr library in this case we will use ZXing and call it from Mulesoft. ![]() ![]() It can generate user provided string/URL to qr code in mule 4. A QR code (can be abbreviated as quick response code) is a type of matrix barcode.Ĭurrently we don't have any Mule component that can generate QR code from provided String/URI in Mulesoft. ![]()
