The image-rendering attribute provides a hint to the browser about how to make speed vs. quality tradeoffs as it performs image processing.

The resampling is always done in a truecolor (e.g., 24-bit) color space even if the original data and/or the target device is indexed color.

Note: As a presentation attribute, image-rendering can be used as a CSS property. See the CSS image-rendering property for more information.

You can use this attribute with the following SVG elements:
