The CanvasRenderingContext2D.save() method of the Canvas 2D API saves the entire state of the canvas by pushing the current state onto a stack.
The drawing state
The drawing state that gets saved onto a stack consists of:
- The current transformation matrix.
- The current clipping region.
- The current dash list.
- The current values of the following attributes:
strokeStyle,fillStyle,globalAlpha,lineWidth,lineCap,lineJoin,miterLimit,lineDashOffset,shadowOffsetX,shadowOffsetY,shadowBlur,shadowColor,globalCompositeOperation,font,textAlign,textBaseline,direction,imageSmoothingEnabled.
Syntax
void ctx.save();
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);
