How to use the svglib.svglib.SvgRenderer function in svglib

def __init__(self, path, renderer):
        self.root_node = load_svg_file(path)
        self.renderer = SvgRenderer(
            path, parent_svgs=renderer._parent_chain + [renderer.source_path]
        )
        self.rendered = False

"Convert an SVG file to an RLG Drawing object."

    # unzip .svgz file into .svg
    unzipped = False
    if isinstance(path, str) and os.path.splitext(path)[1].lower() == ".svgz":
        with gzip.open(path, 'rb') as f_in, open(path[:-1], 'wb') as f_out:
            shutil.copyfileobj(f_in, f_out)
        path = path[:-1]
        unzipped = True

    svg_root = load_svg_file(path, resolve_entities=resolve_entities)
    if svg_root is None:
        return

    # convert to a RLG drawing
    svgRenderer = SvgRenderer(path, **kwargs)
    drawing = svgRenderer.render(svg_root)

    # remove unzipped .svgz file (.svg)
    if unzipped:
        os.remove(path)

    return drawing
