Cannot decode this image,But other software can

Are you trying to decode this image as is shown or through a camera? I'm asking because I also had problems feeding this library images which were generated, but when I took a picture of them, then it worked.

Run our demo through PC and scan this qr code picture in my phone, and decodethe error. Can you decode this image by jsQR?

[totorelmatador]

I've got the same issue with QRCode of that dimension. I'm running the code through PC, not with a camera. Nevertheless jsQR extract binaryData, but the data field is empty.

Any solution to decode binaryData?

FWIW, this is what I get with jsqr@1.3.0:

  binaryData: [
    176, 174, 201, 207,  82, 101,  98, 101,  99,  99,  97,  45,
    178, 169, 191, 205, 163, 172, 214, 187, 206, 170, 203, 188,
    196, 238, 182, 248, 189, 168, 161, 173, 161, 173,  13,  10,
    196, 227, 178, 187, 187, 225, 214, 170, 181, 192, 163, 172,
    213, 226, 212, 211, 194, 210, 181, 196, 182, 254, 206, 172,
    194, 235, 192, 239, 163, 172, 188, 196, 205, 208, 215, 197,
    206, 210, 182, 212, 196, 227, 181, 196, 206, 222, 207, 222,
    203, 188, 196, 238,  13,  10, 176, 174, 196, 227, 163, 172,
    213, 230, 181, 196,
    ... 14 more items
  ],
  data: '羇瞶籌羞罐豬',
  chunks: [
    { type: 'byte', bytes: [Array], text: '' },
    { type: 'kanji', bytes: [Array], text: '羇' },
    { type: 'byte', bytes: [Array], text: '' },
    { type: 'kanji', bytes: [Array], text: '瞶' },
    { type: 'byte', bytes: [Array], text: '' },

    { type: 'kanji', bytes: [Array], text: '羞' },
    { type: 'byte', bytes: [Array], text: '' },
    { type: 'kanji', bytes: [Array], text: '罐' },
    { type: 'byte', bytes: [Array], text: '' },
    { type: 'kanji', bytes: [Array], text: '豬' },
    { type: 'byte', bytes: [Array], text: '' }
  ],

Is that what you expect, @VKingi?

[VKingi]

FWIW，这是我通过jsqr@1.3.0获得的：

  binaryData: [
    176, 174, 201, 207,  82, 101,  98, 101,  99,  99,  97,  45,
    178, 169, 191, 205, 163, 172, 214, 187, 206, 170, 203, 188,
    196, 238, 182, 248, 189, 168, 161, 173, 161, 173,  13,  10,
    196, 227, 178, 187, 187, 225, 214, 170, 181, 192, 163, 172,
    213, 226, 212, 211, 194, 210, 181, 196, 182, 254, 206, 172,
    194, 235, 192, 239, 163, 172, 188, 196, 205, 208, 215, 197,
    206, 210, 182, 212, 196, 227, 181, 196, 206, 222, 207, 222,
    203, 188, 196, 238,  13,  10, 176, 174, 196, 227, 163, 172,
    213, 230, 181, 196,
    ... 14 more items

    { type: 'kanji', bytes: [Array], text: '豬' },
    { type: 'byte', bytes: [Array], text: '' }
  ],

@VKingi是您所期望的吗？

Yes, it seems to be the data I want! After analysis, the qr code data seems to be ANSI coding,Byte [] converted to string error.

[VKingi]

Existing solutions:

// Create the Uint8Array array
let uint8Array = new Uint8Array(code.binaryData);
// encodings: Specify the required encoding
alert( new TextDecoder(encodings).decode(uint8Array) );

Intelligent automatic recognition code would be better ... : )
