How do I display a thumbnail that has been generated after translation

问题

After translating a file to SVF I can see that there is thumbnails that have been generated. How do I use the URN to display these thumbnails?

Thanks!

You can use the Thumbnail endpoint to download the picture, but it requires the Token. So you can, for instance, download it on your server-side (with the token) and redirect the stream to the client-side (from your server).

Here is the thumbnail endpoint: '/modelderivative/' + MD_PROJECT_VERSION + '/designdata/' + urn + '/thumbnail?width=XXX&height=XXX';

And an example (NodeJS)

getThumbnail: function (thumbnailUrn, onsuccess){
    request({
        url: '/modelderivative/v2/designdata/' + thumbnailUrn + '/thumbnail?width=100&height=100';,
        method: "GET",
        headers: {
            'Authorization': 'Bearer ' + token
        },
        encoding: null
    }, function (error, response, body) {
        onsuccess(new Buffer(body, 'base64'));
    });
},

And an NodeJS router:

router.get('/thumbnail', function (req, res) {
   getThumbnail(req.query.urn, function (thumb) {
        res.setHeader('Content-type', 'image/png');
        res.end(thumb);
    });
});

Finally at your HTML you can just use:

<img src="/thumbnail?urn=XxXxXxXxX">
