CanvasRenderingContext2D: imageSmoothingQuality property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The imageSmoothingQuality property of the CanvasRenderingContext2D interface, part of the Canvas API, lets you set the quality of image smoothing.

Note: For this property to have an effect, imageSmoothingEnabled must be true.

Value

One of the following:

"low": Low quality.
"medium": Medium quality.
"high": High quality.

The default value is "low".

Examples

Setting image smoothing quality

This example uses the imageSmoothingQuality property with a scaled image.

HTML
