Examples
Saving the drawing state
This example uses the save()
method to save the default state and restore()
to restore it later, so that you are able to draw a rect with the default state later.
HTML
<canvas id="canvas"></canvas>
JavaScript
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); // Save the default state ctx.save(); ctx.fillStyle = 'green'; ctx.fillRect(10, 10, 100, 100); // Restore the default state ctx.restore(); ctx.fillRect(150, 40, 100, 100);
