Otherwise this script will most probably fail. 103 | 104 | ## Contributing 105 | 106 | - Each decoder is defined in `src` directory as a module. 107 | - Tests are defined in the `tests` directory using `Jest`. 108 | 109 | ## Contributors 110 | 111 | Thanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)): 112 | 113 | 114 | 115 |

116 |   barcode: 'code-2of5',
117 |   // barcodeType: 'industrial',
118 |   options: {    
119 |     // useAdaptiveThreshold: true // for images with sahded portions
120 |     // singlePass: true
121 |   }
122 | })
123 |   .then(code => {
124 |     console.log(code)

Note

153 | 154 |
    155 |
  • This script does not implement logic to locate/rotate barcode in the given image.
    • 156 |
  • Make sure the barcode image is the only thing in the image. Otherwise this script will most probably fail.
