Package Exports

mrz4nodejs
mrz4nodejs/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mrz4nodejs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

Basic steps:

Set the license key.

MrzScanner.initLicense('DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ==');

Create an MRZ scanner object.
```
var obj = new MrzScanner();
```

Load the MRZ model via the mrz4nodejs module path.

var ret = obj.loadModel(path.dirname(require.resolve('mrz4nodejs')));

Call decodeFileAsync() method to recognize MRZ from an image file.

(async function () {
    try {
        var result = await obj.decodeFileAsync('<image-file-path>');
        console.log(result);
    } catch (error) {
        console.log(error);
    }
})();

Parse the MRZ information:

if (result.length == 2) {
    console.log(obj.parseTwoLines(result[0].text, result[1].text));
}
else if (result.length == 3) {
    console.log(obj.parseThreeLines(result[0].text, result[1].text, result[2].text));
}
