SVGPathElement: setPathData() method

pathData

An array of path segments. 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 the absolute commands: 'M', 'L', 'C' and 'Z'.

values

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

None (undefined).

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 code below uses getPathData() method to return the normalized path data as absolute commands. Setting the returned data back to the <path> element using the setPathData() method will result in the different set of path commands in the DOM:

const svgPath = document.querySelector("path");
const pathData = path.getPathData({ normalize: true });

svgPath.setPathData(pathData);

// <path d="M 0 0 L 64 0 L 64 64 L 0 64 Z" />
