Explanation

Hello, I have some PDF documents which contains normal text with portrait orientation and a lateral text on the page side which is oriented in landscape mode.
How can I tell PyPDF2 to extract only text that is oriented in portrait mode as the page orientation and to ignore the landscape text?

I attach an image example

Basically what I want is to extract the series of "example" above and ignore the three "example" rotated by 90 degrees

Thank you in advance for your help
