Extracting images from PDF using pypdfium2 (Python)

I am trying to extract images from a PDF document using this specific library: pypdfium2 (https://pypi.org/project/pypdfium2/).

I would love to use PyMuPDF instead (given it's excellent speed and versatility), but because it uses a copy-left license I CANNOT use it for my workflow. So please don't provide an answer that advises me to use PyMuPDF.

Any suggestions are appreciated. I've looked through the docs but can't seem to find any image extraction methods.

To be clear, I am not trying to convert the PDF pages into images, I am trying to extract images within the document itself (assuming there are any). Images are typically embedded as either jpeg's or png's.
