Yes, pdf.js can do that: https://github.com/mozilla/pdf.js/blob/master/web/viewer.html#L284 https://github.com/mozilla/pdf.js/blob/master/web/viewer.htm.... The purpose of my original comment was to simply say: there’s an existing implementation so if you’re building a pdf file viewer/editor, and you need inspiration, have a look. One of the reasons why mozilla is doing this is to be a reference implementation. I’m not sure why people are upset with this. Though, I could have explained it better.
