Transparent Background

[ogito]

Hi,

How can I make the background transparent?
When I save the canvas image as png, it has a white background.

Thanks,
Ogi

It's been about 6 years since I've even thought about this repository at all so I'm definitely not sure. But have you tried setting a 0 alpha on the background? Something like this?

backgroundColor: 'rgba(255, 255, 255, 0)',

If that doesn't work it might be worth checking upstream https://github.com/timdream/wordcloud for more examples.
