SVGPathElement: getPathData() method

options Optional

An optional object for controlling aspects of the path data retrieval process. This object may contain the following properties:

normalize Optional

A boolean value indicating whether the returned sequence of path segments is converted to the base set of absolute commands ('M', 'L', 'C' and 'Z'), with the values adjusted accordingly.

An array of path segments corresponding to the path data. If no valid path data exists, returns an empty sequence.

Each path segment is an object with the following properties:

type

A path commands. If options.normalize is true this will be one of the absolute commands: 'M', 'L', 'C' and 'Z'.

values

An array or value containing the parameters for the corresponding command.

Consider the following <path> element, drawing a square:

<svg xmlns="http://www.w3.org/2000/svg" width="64" height="64">
  <path d="M0,0 h64 v64 h-64 z" />
</svg>

The getPathData() method will return an array with the raw path data, the same as it's set in the d attribute. With the normalize: true option set, it will return path data normalized to the base set of path commands:

const path = document.querySelector("path");

console.log(path.getPathData());

// Output: raw path data:
// [
//   { type: "M", values: [0, 0] },
//   { type: "h", values: [64] },
//   { type: "v", values: [64] },
//   { type: "h", values: [-64] },
//   { type: "Z", values: [] }
// ]

console.log(path.getPathData({ normalize: true }));

// Output: normalized path data:
// [
//   { type: "M", values: [0, 0] },
//   { type: "L", values: [64, 0] },
//   { type: "L", values: [64, 64] },
//   { type: "L", values: [0, 64] },
//   { type: "Z", values: [] }
// ]
