Unable to read QR code #233

Open AmeyMore98 opened 1 year ago

AmeyMore98 commented 1 year ago

jsQR is unable to read the below QR code, but the Google Lens on my Android phone can.

Here's my code snippet:

const bufferWithAlphaChannel = await sharp(
   imgBuffer
)
    .ensureAlpha()
    .raw()
    .toBuffer();

const result = jsQR(
    new Uint8ClampedArray(bufferWithAlphaChannel),
    width,
    height
);

Am I doing something wrong?
