bezier-tweaker

Small UI for adjusting 1-dimensional bezier curves.

Creates a new UI for adjusting a bezier curve, returning an EventEmitter with the following properties:

  • tweaker.el: the SVG element containing the UI.
  • tweaker.points: the Y positions for each control point, ranging from 0 to 1.
  • tweaker.interpolate: an interpolation function that takes an X value between 0 and 1, returning a Y value between 0 and 1. Useful for live-updating animations.

Takes the following options:

  • precision: The amount of points to draw in the line. Defaults to 50.
  • degrees: Number of points to use in the curve. Defaults to 4.
  • padding: Padding around the UI, in pixels. Defaults to 50.
  • height: Height (not including padding), in pixels. Defaults to 200.
  • width: Width (not including padding), in pixels. Defaults to 200.
  • control: Pass in a custom array of control points.

Emitted every time the curve is updated, passing along the array of control points (also available at tweaker.points) as the first argument.
