so like ocr but not recognizing characters and words but recognizing the layouted structure and transforming it into content markup and layout markup?
replyThat's a way to view it!
replyThe reason I'm not falling back on OCR is because the general case is full of things, like math equations and inset graphics/diagrams, that can't be OCR'd. The only robust way to deal with those is to treat them as graphical atoms: "this bounding box can be moved around, but should not be split up into pieces".
