Hi, I'm currently implementing this API and I would like to know if you could already have an answer/example to this point:

save a preliminary result to give user feedback that something is happening

Is it possible to update some sort of status field. Currently I have a hard time understanding how I let the user know what the progress of the request process is.

I'm using it for WholeSlide analysis combined with the 'imagenotification' endpoint and would like to know from which flavours to pick to show the status of my algorithm. Currently from the API documentation it is only clear to me how to post results as 'annotation' e.g. polygons.

Sorry @daangeijs for the late reply. My intent is to recommend creating a polygon. Currently working on the details of appropriate placement/size etc. The label text of polygons can be updated, and thus the text is where I suggest progress reports are sent.

Here's an excerpt of the relevant code, creating a rectangle polygon surrounding the entire slide with the label top-right:

    text = "wsi processing. 0%"
    max_y = metadata["imageSize"]["height"] / metadata["imageSize"]["width"]

    response_result = {
        "type": "primitive",
        "content": {
            "style": {"fillStyle": None, "size": None, "strokeStyle": "#FFA500"},
            "polygons": [{"points": [{"x": 0.0, "y": 0.0}, {"x": 1.0, "y": 0.0}, {"x": 1.0, "y": max_y}, {"x": 0.0, "y": max_y}]}],
            "labels": [
                {"location": {"x": 1.0, "y": 0.0}, "label": text}
            ],
        },
    }

Since there is now a full example in #7 which will be merged soon, I'll close this issue.
