splinebox.spline_curves.HermiteSpline.

to_json

HermiteSpline.to_json(path, version=1)

Saves the spline as a json file.

Parameters:

pathstr or pathlib.Path

The path where the json file should be saved.

versionint

The version of the json file. Default is latest version.

Examples

>>> spline = splinebox.Spline(M=3, basis_function=splinebox.B1(), closed=True)
>>> spline.knots = np.array([[0.8, 1.2], [0.7, 1.5], [1.1, 0.3]])

Save the spline to file…

>>> path = path_to_some_directory / "spline.json"
>>> spline.to_json(path)

Let’s take a look at the file…

>>> print(open(path, "r").read())
{
  "version": 1,
  "M": 3,
  "basis_function": "B1",
  "closed": true,
  "control_points": [
    [
      0.8,
      1.2
    ],
    [
      0.7,
      1.5
    ],
    [
      1.1,
      0.3
    ]
  ]
