How can we make a request to the image server now ?

[vannary]

Here is our previous command: https://research.cytomine.be/api/abstractimage/10828059/imageservers.json

The code error is 403.

Hi, If you have a 403 error, it means you don't have rights to access the resource. Are you sure your are authenticated in your browser when requesting this URL ?

Anyway, this service is now deprecated. With the last Cytomine-ULiege version, an Image Instance has a collection of slices (SliceInstance) so that an image can hold several C,Z,T planes. In the case of a regular 2D image, the collection has only one item (0,0,0) . The slice instance has the attributes:

• imageServerUrl
• path

These 2 attributes help you to get what was returned by the now deprecated imageservers.json request:

 imageServer = ${slice.imageServerUrl}/slice/tile?zoomify=${slice.path}

To get these attributes with the Java Client you have to use at least the v2.2.0 release of this repo. The result can be achieved like this:

int image_id = 123
Collection<SliceInstance> c = new Collection<>(SliceInstance.class, 0,0);
        c.addFilter("imageinstance", String.valueOf(image_id));
        c.fetch();

        for (int i = 0; i < c.size(); i++) {
            System.out.println(c.get(i).getStr("imageServerUrl"));
            System.out.println(c.get(i).getStr("path"));
            System.out.println(c.get(i).getStr("imageServerUrl") + "/slice/tile?zoomify=" + c.get(i).getStr("path"));
        }

We get the ImageServer, thanks.

But now, how can we download the picture. ? previoulys downloadPictureAsBufferedImage
