2020年12月6日 · You could certainly build something based on the Xpdf code. You'd need to construct a new OutputDev subclass (look at SplashOutputDev and TextOutputDev), and monitor the drawing operations for things that look like colored boxes, symbols, etc. You'll need to take into account the possibility that those items can be drawn in any order.

2020年9月4日 · The version of pdftotext that's part of the Xpdf tools doesn't have a "-row" option. In any case, it sounds like you're looking for something that can do automated table detection. I've been thinking about that problem for a while, but I don't have any code (yet) that does it.

2019年5月21日 · That disables a heuristic in pdftotext that tries to guess font encodings. In some circumstances, extraction works better without the heuristic.
