Is it possible to adjust the points on a current path using Snap?

I have an SVG containing a path element:

<path d="M54.7,0.8 L111.8,73.4 L79.9,126.1 L27.9,128.7 L0.5,74.2 L54.7,0.8 Z" id="Shape"></path>

After exploring the meanings of SVG paths, I've learned that:

  • M signifies moving to a point
  • The Ls draw lines
  • Z closes the path, producing a polygon

Despite understanding the basics, I'm facing challenges when attempting to manipulate the path using SnapSVG:

var graph = Snap(".graph");
var item = graph.select('#after #Shape');

While searching through the Snap documentation, I have been unable to find information on modifying existing paths. Although I have looked into the item's paper.path, I could not find any examples of path modifications, only instructions on creating new paths.

How can I alter an existing path in SnapSVG? My goal is to animate the transition from the old shape to the new one.

Answer №1

To create animations for the d attribute (known as path descriptions) in SVG using SnapSVG, follow these steps:

var drawing = Snap(".drawing");
var shape = drawing.select('#element #Path');

Retrieve the current path points:

shape.attr('d')

Next, animate the path points:

shape.animate({
  d: "M81.8,0.1 L146.8,85.1 L124.1,164.4 L39.7,164.4 L0.6,79.7 L81.8,0.1 Z"
}, 1500, mina.easeout)
