How can I add meta data to the picture in Google Photos - google-photos

Question

I just created my first album via api, uploaded a picture and added to to my new album. But how can I specify the timezone, the camera data, the location, etc?
Do I really need to embed those information via exif? In that case I would need to manipulate the image data which I want to avoid.

Answer 1

This is my workaround. I add the information via exif in nodejs:
request.get('http://example.com/foto.jpg')
.pipe(exifEnricher)
.pipe(request.post('https://photoslibrary.googleapis.com/v1/uploads', {
headers: {
'User-Agent': 'MyService',
'Authorization': 'Bearer ' + token,
'Content-type': 'application/octet-stream',
'X-Goog-Upload-File-Name': 'Filename.jpg',
'X-Goog-Upload-Protocol': 'raw'
}
}, function(error, uploadResponse, uploadToken) {
if(error) {
response.end(error);
} else {
request.post('https://photoslibrary.googleapis.com/v1/mediaItems:batchCreate', {
headers: {
'User-Agent': 'MyService',
'Authorization': 'Bearer ' + token,
'Content-type': 'application/json'
},
json: {
"albumId": "abcdef...",
"newMediaItems": [
{
"description": "Haustür X",
"simpleMediaItem": {
"uploadToken": uploadToken
}
}
],
"albumPosition": {
"position": "FIRST_IN_ALBUM"
}
}
}, (error, addToAlbumResponse, addToAlbumBody) => {
if(error) {
response.end(error);
} else {
response.end(JSON.stringify(addToAlbumBody));
}
});
}
}));
const exifEnricher = new Transform({
transform(chunk, encoding, callback) {
if(chunk[0] === 255 && chunk[1] === 216) {
const data = chunk.toString("binary");
const exifObj = piexif.load(data);
exifObj["GPS"][piexif.GPSIFD.GPSVersionID] = [2, 2, 0, 0];
exifObj["GPS"][piexif.GPSIFD.GPSLatitudeRef] = "N";
exifObj["GPS"][piexif.GPSIFD.GPSLatitude] = [[lat_degree, 1], [lat_minutes, 1], [lat_seconds_x_10, 10]];
exifObj["GPS"][piexif.GPSIFD.GPSLongitudeRef] = "E";
exifObj["GPS"][piexif.GPSIFD.GPSLongitude] = [[lon_degree, 1], [lon_minutes, 1], [lon_seconds_x_10, 10]];
exifObj["GPS"][piexif.GPSIFD.GPSAltitudeRef] = 0;
exifObj["GPS"][piexif.GPSIFD.GPSAltitude] = [alt_in_cm, 100];
exifObj["0th"] = exifObj["0th"] || {};
exifObj["0th"][piexif.ImageIFD.Software] = "MyService";
exifObj["0th"][piexif.ImageIFD.Make] = "Brand";
exifObj["0th"][piexif.ImageIFD.Model] = "Device Name";
exifObj["0th"][piexif.ImageIFD.DateTime] = dateFormat(new Date(), "yyyy:mm:dd HH:mm:ss");
const exifbytes = piexif.dump(exifObj);
const newData = piexif.insert(exifbytes, data);
callback(null, Buffer.from(newData, 'binary'))
} else {
callback(null, chunk)
}
}
});
