sizes

The sizes array determines the resolution of one or more images to be created in the request.

Specify an object consisting of width and height properties, and optionally a filename property if you wish to specify the resulting image's filename for the resolution.

Not specifying a filename will result in a random identifier being used.

{
    "template": "sample-image",
    "sizes": [
        {
            "width": 1080,
            "height": 1080,
            "filename": "my-image.png"
        }
    ]
}

You can also include modifiers in the filename specifier to aid in filename generation:

{
    "template": "sample-image",
    "sizes": [
        {
            "width": 1080,
            "height": 800,
            "filename": "output-%wx%h.png"
        }
    ]
}
