acrobat pdf reader blocks out filled in boxes

Delete the following file in the local appdata folder: For Acrobat Reader: IconCacheRdr.dat.

Mutool convert -o output/%d/1.png tmp1. Meanwhile, follow these steps as a workaround: Open the local appdata folder: C:UsersAppDataLocalAdobeAcrobatDC.

Gs -o tmp2.pdf -sDEVICE=pdfwrite -dFILTERTEXT tmp1.pdf &>/dev/null If ((($max_pages > 1) & ($max_pages /dev/null this is the case for scanned PDFs processed by OCR sofware - such as pdfsandwich or Adobe Acrobat - that adds 'invisible' text blocks on top of the image, so that you can select the text). distinguish between fully scanned and full/partial textual PDFs), this solution is not able to distinguish between full-textual PDFs and scanned PDFs that also have text within them (e.g. Print('not fully scanned PDF - text is present')Īlthough this answers your question (i.e. Print('fully scanned PDF - no relevant text')

Text_perc = get_text_percentage('my.pdf') Total_text_area = total_text_area + text_area R = fitz.Rect(b) # rectangle where block text appears Total_page_area = total_page_area + abs(page.rect) When opening the PDF with Reader or Acrobat Pro the forms field data is blank. If the returned percentage of text is very low, the document is So here is how I install the modules: pip3 install fitzĪnd here is the Python 3 implementation: import fitzĭef get_text_percentage(file_name: str) -> float:Ĭalculate the percentage of document that is covered by (searchable) text. Moreover, it is important to install fitz BEFORE PyMuPDF, otherwise it provides some weird error about a missing frontend module (no idea why). The following code has been tested with Python 3.7.9 and PyMuPDF 1.16.14. You need to install fitz and PyMuPDF modules.

Building on top of Rahul Agarwal's solution, along with some snippets I found at this link, here is a possible algorithm that should solve your problem.
