xmp-reader
Extracts some commonly used XMP/RDF metadata tags from JPEG files. Does not pretend to be a complete metadata management tool, but allows you to extract some information other EXIF-management tools on NPM fail to retrieve. Was originally created only to extract a Description field baked into my JPEGs by Google's Picasa.
Usage
To install the module add it to your project's package.json
dependencies or install manually running:
npm install xmp-reader
Then pull it in your code:
const xmpReader = require('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:
