public interface SVGGeometryElement extends SVGGraphicsElement
Represents SVG elements whose rendering is defined by geometry with an equivalent path, and which can be filled and stroked.

  • Method Details

    • getPathLength

      SVGAnimatedNumber getPathLength()
      Gets the read-only pathLength attribute, which is the author's computation of the total length of the path, in user units.

      The pathLength attribute has no effect on percentage distance-along-a-path calculations.

      Returns:
      the total length of the path, in user units.

    • getTotalLength

      float getTotalLength()
      Get the length of the path.
      Returns:
      the length of the path, in user units.

    • getPointAtLength

      SVGPoint getPointAtLength(float distance)
      Gets the point at a given distance along the path.

      When getPointAtLength(distance) is called, the following steps are run:

      1. If current element is a non-rendered element, and the UA is not able to compute the total length of the path, then throw an InvalidStateError.
      2. Let length be the user agent's computed value for the total length of the path, in user units.

        As with getTotalLength, this does not take into account the pathLength attribute.

      3. Clamp distance to [0, length].
      4. Let (x, y) be the point on the path at distance distance.
      5. Return a newly created, detached DOMPoint object representing the point (x, y).

      Parameters:
      distance - the distance.
      Returns:
      the point at a given distance along the path.
