how to export as png/jpg? #30

Closed zillionare closed 3 years ago

zillionare commented 3 years ago

the lib is great. One question though, I'd like use this lib to draw a graph and then export as png/jpg, how to achieve that?

huww98 commented 3 years ago

I don't know. This can be quite complex, and I think is out of the scope of this lib.

For the WebGL part, canvas API should allow you to export it to image. But this lib also uses SVG and some HTML, which you need to deal with yourself. Maybe render them in another canvas. I believe there are plenty of libraries for this on GitHub.

thanks. Maybe add this feature in future?
