backend_for_path

lsst.images.serialization.backend_for_path(path: str | ParseResult | ResourcePath | Path) → Backend

Return the Backend for path based on its file extension.

Supported extensions: .fits / .fits.gz (FITS), .sdf / .ndf (NDF), and .json (JSON). The NDF and FITS backends are imported lazily so optional dependencies (e.g. h5py) are only required when actually used.

Raises

ValueError

If the extension is not recognised.
