Question

I have a PDF document but I must put my own image on it. It’s an official document and I must apply an image with the text “example” to the whole page.

Is there any way to solve this problem in python?

(text in the document is curves)

Look into pypdf. You might use something like the following code to apply an overlay:

page = PdfReader("document.pdf").pages[0]
overlay = PdfReader("overlay.pdf").pages[0]
page.merge_page(overlay)

Put any overlay you want, including "Example", into overlay.pdf.
Personally, I prefer PDFTK, which, while not strictly Python, can be invoked from a script with os.system(command).
