kopparmora-xmp-reader

xmp-reader

Extracts XMP/RDF metadata tags from JPEG files. Does not pretend to be a complete metadata management tool, but allows you to extract information other EXIF-management tools on NPM fail to retrieve. This package has been forked from xmp-reader and has been modified to include all metadata tags it finds in an image.

Usage

To install the module add it to your project's package.json dependencies or install manually running:

npm install kopparmora-xmp-reader

Then pull it in your code:

const xmpReader = require('kopparmora-xmp-reader');

Now you can either feed it a file name:

xmpReader.fromFile('/path/to/file.jpg', (err, data) => {
  if (err) console.log(err);
  else console.log(data);
});

Or a buffer:

xmpReader.fromBuffer(buffer, (err, data) => {
  if (err) console.log(err);
  else console.log(data);
});

Both methods above return a promise, you can use that instead of the callback:

xmpReader.fromBuffer(buffer).then(
  (data) => console.log(data),
  (err) => console.log(err)
);

Output will look something like that, depending on your metadata:

{
    "raw": {
        "MicrosoftPhoto:Rating": "50",
        "dc:title": "Title",
        "dc:description": "Title",
        "dc:creator": "Alexander Kuznetsov",
        "Iptc4xmpCore:Location": "New York",
        "MicrosoftPhoto:LastKeywordXMP": ["tag1", "tag2"],
        "MicrosoftPhoto:LastKeywordIPTC": ["tag1", "tag2"],
        "xmp:Rating": "3"
    },
    "rating": 3,
    "title": "Title",
    "description": "Title",
    "creator": "Alexander Kuznetsov",
    "location": "New York",
    "keywords": ["tag1", "tag2"]
}

raw property contains vendor-specific tag names.
