CanvasRenderingContext2D: shadowOffsetX property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The
CanvasRenderingContext2D.shadowOffsetX
property of the Canvas 2D API specifies the distance that shadows will be offset
horizontally.
Note:
Shadows are only drawn if the
shadowColor
property is set to
a non-transparent value. One of the shadowBlur
, shadowOffsetX
, or
shadowOffsetY
properties must
be non-zero, as well.
Value
Examples
Moving a shadow horizontally
This example adds a blurred shadow to a rectangle. The
shadowColor
property sets its
color, shadowOffsetX
sets its offset 25 units to the right, and
shadowBlur
gives it a blur level
of 10.
HTML
<canvas id="canvas"></canvas>
JavaScript
const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");
// Shadow
ctx.shadowColor = "red";
ctx.shadowOffsetX = 25;
ctx.shadowBlur = 10;
// Rectangle
ctx.fillStyle = "blue";
ctx.fillRect(20, 20, 150, 100);
