in_rectangle

The in_rectangle parameter is used to specify the constraints on the position of a region of interest (RoI).

[{
    "FindImage": {
        "_ref": 1,
        "constraints": {
            "unique_id": ["==", 34]
        },
        "blobs": true
    }

Successful response:

    "FindImage": {
        "blobs_start": 0,
        "returned": 1,
        "status": 0
    }
}, {
    "FindBoundingBox": {
        "entities": [{
            "_coordinates": {
                "height": 40,
                "width": 40,
                "x": 120,
                "y": 50

            "_label": "Dog",
            "id": null
        }],
        "returned": 1,
        "status": 0
    }
}]

where x and y are the coordinates of the upper left corner of the rectangle and w and h are the width and height.

If in_rectangle is specified, the RoIs returned must be fully within the boundaries indicated by the given rectangle parameters.
