Hello to all!

i use zxing for scan QR from image from gallery:

RGBLuminanceSource rgbls = new RGBLuminanceSource(img.getWidth(), img.getHeight(), img.getRGB());

Binarizer binarizer = new HybridBinarizer(rgbls);

BinaryBitmap binBitmap = new BinaryBitmap(binarizer);

Result qrCodeResult = new MultiFormatReader().decode(binBitmap);

If image is sterile how https://ib43.ru/qr.gif then all ok

but if image like https://ib43.ru/qr3.jpg than the program hangs

Desktop version of zxing hood work with both via BufferedImageLuminanceSource(img)

How i can scan QR code from image, not from camera?

Hi,

is this related to Codename One?

not really. There is simply no choice of libraries, but the proposed one has a problem for me. Maybe someone has already come across and decided

We support 3 separate QR libraries.

Is this a question about embedding the zxing library into Codename One?
