MatrixToImageWriter(int ARGOncolor,int ARGOffcolor) not changing colour of the barcode

Bug Reports

I was using this function to create a colorful barcode but the output was plain black& white barcode.
This is the part where I used a function I created RGB which takes 2 integers (red,green,blue values) as parameter & returns an ARGB int value to work with. The code was working till last night but I don’t know for some reason it’s not working now.
BitMatrix matrix = writer.encode(text, BarcodeFormat.CODE_128, 500, 300); MatrixToImageConfig conf = new MatrixToImageConfig(RGB(0,0,255),RGB(0,255,0)); BufferedImage qrcode = MatrixToImageWriter.toBufferedImage(matrix, conf); File outputfile = new File(path); ImageIO.write(qrcode, "png", outputfile);

Here’s the declaration of the RGB function:- private static int RGB(int red,int green,int blue) { int rgb=(65536*red+256*green+blue); return ((16777215-rgb)*(-1)); }

Here’s the resultant barcode128 image

And here’s the console output:- On Color = -16776960 Off Color = -16711935

It’s working now. Thanks a lot man. You’re a lifesaver

Works fine for me. Are you sure you’re reading the right path? Ex:

    Code128Writer writer = new Code128Writer();
    BitMatrix matrix = writer.encode("foobar", BarcodeFormat.CODE_128, 500, 300);
    MatrixToImageConfig conf = new MatrixToImageConfig(0xFF00FF00, 0xFF0000FF);
    BufferedImage qrcode = MatrixToImageWriter.toBufferedImage(matrix, conf);
    File outputfile = new File("/tmp/out.png");
    ImageIO.write(qrcode, "png", outputfile);
