Then I don't know what you mean. When you drag over them, they turn blue because you _have_ selected them (drag.png, apologies for the size). Then you can paste them into, say, a bash shell command line (pasted.png, the box at the right is the inactive cursor). But why do you want to select part of a PDF like that when _you_ generated it? I often do that with _other_ people's PDFs when I want to get at their text. The rendition of the dragged area is entirely a function of the viewer you're using. Xpdf always shows a rectangle and lifts just the text therein, rather than being constrained by the lines of text (xpdf.png, more apologies). However, I think it mixes up its encodings so the pasted text makes little sense. > >The greatest zoom I can manage is 1600%, and I can't see the joins. > >The H bars were just to follow each of your characters with something. > > I'm pretty sure it's just some kind of rounding error in my PDF > viewer, but you can see a seam between the first and second bar to > right of the kanji in the second row (seam.png). > > Also note that the bars on the kana row are a lot longer and thinner > than the kanji row. That looks a lot like evince that you're using. Very good for reading Chase credit card statements and encrypted PDFs, which xpdf can't manage, but I hate the interface. Anyway, my guess is that evince treats keeping the characters _as_ individual characters as its priority, whereas xpdf tries to render what will print. One really needs an armoury of PDF viewers. So now the question becomes what do you want to produce these PDFs for, and how are you going to ascertain which browser the consumers are using? If I were sending them to my printers, my expectations (and theirs) would be the sort of copies that I've shown magnified. Cheers, David.
