To keep drawing on a canvas when scrolling, one option is to listen for scroll events on the page and adjust the position of the drawing accordingly. Here are the steps to achieve this:
1 2 |
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); |
1 2 3 4 5 6 7 8 |
window.addEventListener('scroll', () => { // Update the position of the canvas drawing based on the scroll position const scrollX = window.scrollX; const scrollY = window.scrollY; // Reposition the canvas drawing ctx.translate(-scrollX, -scrollY); }); |
1 2 3 4 5 6 7 8 9 10 |
function draw() { // Reset the canvas translation ctx.setTransform(1, 0, 0, 1, 0, 0); // Clear the canvas ctx.clearRect(0, 0, canvas.width, canvas.height); // Redraw your drawing // ... } |
With these steps, the canvas drawing will stay in place relative to the page while scrolling. It's important to note that this method may not work well for very complex or performance-intensive drawings, as constantly redrawing the canvas on scroll can slow down the page.
