javascript - How to grab images generated by canvas

Question

I need to synthesize images. I wonder if I can directly capture the image generated by canvas in the background and then return it to the front end?

To download, use the download attribute added in the a tag in HTML or download through the backend. For details, you can also refer to the canvas image download
