Get Started

Install svg.js, svg.select.js and svg.resize.js using npm:

bash
npm i @svgdotjs/svg.js @svgdotjs/svg.select.js @svgdotjs/svg.resize.js

Or get it from a cnd:

html
<script src="https://unpkg.com/@svgdotjs/svg.js"></script>
<script src="https://unpkg.com/@svgdotjs/svg.select.js"></script>
<script src="https://unpkg.com/@svgdotjs/svg.resize.js"></script>

Select and resize a rectangle using this simple piece of code:

ts
var canvas = new SVG().addTo("body").size(500, 500);
canvas.rect(50, 50).fill("red").select().resize();

Usage

Activate resizing

ts
rect.select().resize();

Deactivate resizing

ts
rect.resize(false);

Preserve aspect ratio, resize around center and snap to grid:

ts
rect.resize({
  preserveAspectRatio: true,
  aroundCenter: true,
  grid: 10,
  degree: 0.1,
});

Options

  • preserveAspectRatio: Preserve the aspect ratio of the element while resizing
  • aroundCenter: Resize around the center of the element
  • grid: Snaps the shape to a virtual grid while resizing
  • degree: Snaps to an angle when rotating

Events

While resizing, a resize event is fired. It contains the following properties (in event.detail):

  • box: The resulting bounding box after the resize operation
  • angle: The resulting rotation angle after the resize operation
  • eventType: The type of resize operation (the event fired by the select plugin)
  • event: The original event
  • handler: The resize handler
ts
rect.on("resize", (event) => {
  console.log(event.detail);
});

Migration from svg.js v2

  • The option naming changed a bit. Please double check
  • The former events were removed. The resize event now serves the same purpose
