Add a background

Background is an optional ArFrame attribute to display any image behind pipeline visualization.

Load and display ArFrame background

ArFrame.background can be enabled with a dedicated JSON entry.

Here is an extract from the JSON ArFrame configuration file where a background picture is loaded and displayed:

{
    "argaze.ArFeatures.ArFrame": {
        "name": "My FullHD screen",
        "size": [1920, 1080],
        ...
        "background": "./bosch.png",
        ...
        "image_parameters": {
            ...
            "background_weight": 1
        }
    }
}

Now, let's understand the meaning of each JSON entry.

background

The path to an image file on disk.

background_weight

The weight of background overlay in ArFrame.image between 0 and 1.
