How to use image as a mask?

[gettonet]

Hi, I am trying to use the attached image as a mask, so the middle section's not filled. It works in your demo, but I cannot figure out how to implement this on a web page, using only wordcloud2.js. It is a simple rectangle shape, but I obviously cannot use your "shape generator" since the center needs to be excluded from drawing.
Any help is much appreciated.

I also face the problem. So I looked the source code and changed the code like this.

The code is no long reports errors. But the canvas is still blank. Please let me know if anyone knows the answer.
