It actually seems as if Moon+ reader can make annotations and highlights even in reflow mode, which no other PDF reader can do (apart from Repligo, which however is very bad at reflow).
However, every time I tried to add a highlight to a PDF in reflow mode in Moon+ reader, I got an error message saying that the highlight could not be created.
Does anyone know what could be the problem here? |
The PDF format does allow the user to annotate, highlight, and add notes to already created PDF files (see
Wikipedia). I've tried a few such kind of software. The annotation seems to be somewhat portable across apps. But I doubt it is 100% or close to 100% compatible in practice.
I haven't tried Moon+ reader recently. But I don't think PDF reflow is good enough currently, especially for technical papers/books with math symbols, graphs and illustrations. Whatever format is used to represent the result of a PDF reflow operation will put you back in a situation similar to that of EPUB format.
I think the problem of portable EPUB annotation is due to the lack of motivation of the industry.
