gnu-octave / octave-qr Goto Github PK

Hi, is my first time in this site and i ask a favor.

When i run your code, i get QRCode code, and i understand that represents the encoded image of the barcode

I'm trying with the next method for get the image:
private static void createQRImage(ByteMatrix matrix) throws WriterException, IOException {
String qrCodeText = "AQUI IRIA LA CADENA LARGA QUE SE SOLICITA";
String filePath = "C:/Users/rcn_f/Desktop/QrDemo.png";
String fileType = "png";
File qrFile = new File(filePath);
QRCodeWriter qrCodeWriter = new QRCodeWriter();
int matrixWidth = matrix.getWidth();
BufferedImage image = new BufferedImage(matrixWidth, matrixWidth, BufferedImage.TYPE_INT_RGB);
image.createGraphics();
Graphics2D graphics = (Graphics2D) image.getGraphics();
graphics.setColor(Color.WHITE);
graphics.fillRect(0, 0, matrixWidth, matrixWidth);
// Paint and save the image using the ByteMatrix
graphics.setColor(Color.BLACK);
for (int i = 0; i < matrixWidth; i++) {
for (int j = 0; j < matrixWidth; j++) {
if (byteMatrix.get(i, j)) { // here is my problem i think that i need a sustitute for get (x, y)
graphics.fillRect(i, j, 1, 1);
}
}
}
ImageIO.write(image, fileType, qrFile);
}

I appreciate your help infinitely
