Scale

tomni.json_operations.scale_json(json_object: dict, scaling_factor: float)[source]

Scale a JSON object (ellipse or polygon) by a specified scaling factor.

Parameters

json_object (dict) – JSON object following the standard format (ellipse or polygon).
scaling_factor (float) – The multiplier to scale the object. A value of 1.0 keeps the object unchanged.

Returns

A new JSON object scaled by the provided factor.

Return type

dict

Raises

ValueError – If the JSON object type is not supported.

Example:

json_object = {
    "type": "ellipse",
    "center": {"x": 100, "y": 200},
    "radiusX": 50,
    "radiusY": 100,
    "angleOfRotation": 0,
    "id": "12345-abcde"}
scaling_factor = 2

result = {
    "type": "ellipse",
    "center": {"x": 200, "y": 400},
    "radiusX": 100,
    "radiusY": 200,
    "angleOfRotation": 0,
    "id": "12345-abcde"}
