The issue I see is that there are two things (if I use Mac OS X Preview to do them): - highlights - annotations Highlights are for example drawn by PDF.js even if you don't enable annotation support. They are also not returned through their annotations API. So for me it seems that they are stored differently. Also annotations looks like that have only rectangle locations defined, while drawn highlights can follow the text nicely. So I wonder how those highlights are stored. Once we get them somehow from PDF.js, we can look into how to convert them to open annotation standard. But for now I don't see a way how to extract them from PDF.js. I would love if they would be part of what their annotation API returns. Mitar -- http://mitar.tnode.com/ https://twitter.com/mitar_m
