I’m drawing a path2D SVG shape on canvas. The problem is that the moveTo function does not seem to work when using SVG data.
The problem is illustrated in this codepen. https://codepen.io/grasmachien/pen/rNaJeBN
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); let p = new Path2D('M10 10 h 80 v 80 h -80 Z'); p.moveTo(100,100) ctx.fill(p);
Is there a way to move the path without moving the canvas?

Answer
Use the transform to move the path
Using CanvasRenderingContext2D.translate
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); let p = new Path2D('M10 10 h 80 v 80 h -80 Z'); ctx.translate(100, 100); ctx.fill(p);
or using CanvasRenderingContext2D.setTransform
let p = new Path2D('M10 10 h 80 v 80 h -80 Z'); ctx.setTransform(1, 0, 0, 1, 100, 100); // Also resets the transform before applying ctx.fill(p);
or using CanvasRenderingContext2D.transform
let p = new Path2D('M10 10 h 80 v 80 h -80 Z'); ctx.transform(1, 0, 0, 1, 100, 100); ctx.fill(p);
