shape-points

Generate points for simple shapes and curves: arcs, rectangles, rounded rectangles, circles, ellipses, bezierCurveTo, bezierCurveThrough (i.e., bezier curves through specific points)

rationale

I needed to find the points of a rounded rectangle. Then I had fun adding lots of other shapes and curves.

installation

yarn add shape-points

npm i shape-points

programmatic example

import * as ShapePoints from 'shape-points'

// alternatively: 
// const roundedRect = require('shape-points').roundedRect

const points = ShapePoints.roundedRect(125, 100, 200, 100, 30)

// assuming a canvas context was set up
context.moveTo(points[0], points[1])
for (let i = 2; i < points.length; i += 2)
{
    context.lineTo(points[i], points[i + 1])
}
context.stroke()
