I have a pdf file which includes graphs, not in image format. Is there any way to process pdf file using content streams and fetch graphs out of it

    Your question is about `pdfbox`, so why tag `itext`? – Amedee Van Gasse Sep 16 '19 at 08:15
  • I was unsure about it, seems linked with pdf creation extraction. that why I used. – Deepak Dhaka Sep 16 '19 at 08:24

  • @TilmanHausherr, I'm new in manipulating pdf objects, can you guide how it is related? I need only graphs that are present in pdf, not anything else like table, text, image. – Deepak Dhaka Sep 16 '19 at 12:04
  • There is no such concept as a "graph" in PDF. The answer I linked to describes how to collect line coordinates. So if your graph is vector graphic within a table, you'll end up with the table and the graph details and will have to sort it out. – Tilman Hausherr Sep 16 '19 at 12:27
