How to extract images from a PDF？ #278

How to extract images from a PDF when get_page_images doesn't work.

gamcoh commented 2 months ago

Did you find any help @liubaochuan ?

The relevant part of the spec is "8.9 Images". There seem to be two ways to embed an image: as an XObject and as an inline image (8.9.7 Inline Images). Inline images are embedded in the content stream of the page. I'm pretty sure that lopdf does not find such images.

A sample PDF would really help to confirm my suspicion (or help fix a bug).

Maybe related to #78.
