Filter vertically strings

[argv1]

Hello dear developers,
is there a possibility to ignore a string that is printed vertically on each page in the lower left corner? Currently the single letters/digits are split and set in front of the corresponding lines.
Thank you in advance for your guidance.

It's fairly difficult to provide a confident answer without seeing the specific PDF in question, but you might try using page.crop to focus just on the core area of the PDF (see documentation in README.md), or page.filter(lambda x: x.get('upright') != 0) to remove vertical characters.
