使用Javascript是否可以获取由线性或径向渐变呈现的背景图像？

Question

I'm specifically interested in gradients but I suppose the question applies to images rendered with any method, such as data:image/svg+xml;...

Is it possible?

ETA:

This was possible by rendering the gradient onto a canvas. For anyone interested in saving a .png of a CSS3 linear or radial gradient, go to:

Design your gradient, click the CVS (canvas) button and right-click the gradient preview to save it as an image.

Answer 1

A DOM element with a CSS gradient background, no way to do that without a screen shot utility.

However, if you drew a gradient in a canvas element (and any other graphics in the canvas element), you could export the graphic of the canvas element as a JPG or PNG using JavaScript in the browser. See this question .

通过截图吗？
