CanvasRenderingContext2D.restore() - Web APIs 编辑

The CanvasRenderingContext2D.restore() method of the Canvas 2D API restores the most recently saved canvas state by popping the top entry in the drawing state stack. If there is no saved state, this method does nothing.

For more information about the drawing state, see CanvasRenderingContext2D.save().

Syntax

void ctx.restore();

Examples

Restoring a saved 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);
