phantomjs: Save a base64 string as a file(png)

Question

Yes I did it in Nodejs but I can't in PhantomJS.

imgContent = '...base64...string';
imgContent = imgContent.replace(/^data:image\/png;base64,/, "");
chart_path = "/charts.png";

fs.write(chart_path, new Buffer(imgContent, 'base64'), 'w');

The error message:

ReferenceError: Can't find variable: Buffer

Answer 1

I'm not sure is it best solution, but it works fine for me.

// ...

fs.write(chart_path, atob(imgContent), 'b');

Phantomjs version 2.1.1.
