The mupdf is a good open source pdf reader. It meets almost all of my requirements except it can't reader pdf from right-to-left. Does anybody have any idea about it?
Actually my understanding for RTL is that I can navigate to the last page first. Then go from there. Buy my question is how am I suppose to know a pdf is a RTL one?
There isn't any way to know the reading direction of a PDF file. It seems like what you want is not right-to-left but back to front, or bottom to top.
