This page has a large amount of drawings, which could raise initial suspicions to start with: >>> doc=fitz.open("PeerJ_2021_May_28_d5de.pdf")
>>> page=doc[12]
>>> paths = page.get_drawings()
>>> len(paths)
502
>>>If you then look at the amount of single draw commands: >>> draws = 0
>>> for p in paths:
draws += len(p["items"])
>>> draws
4623
>>>... it becomes clear that something significant is being done on the page. I have a script somewhere which helps separating drawings into disjoint subsets. Once you have those, join associated rectangles and make pixmaps, which can be separately be OCRed. |
