How might one extract all images from a pdf document, at native resolution and format? (Meaning extract tiff as tiff, jpeg as jpeg, etc. and without resampling). Layout is unimportant, I don't care were the source image is located on the page.
I'm using python 2.7 but can use 3.x if required.

In preferences/general check the box that says 'use fixed resolution for snapshot tool' and set the resolution to your liking e.g., 300ppi or even higher. Then take a snapshot (tools/select & zoom/snapshot tool) and it will copy a high res copy to your clipboard. Then paste it from your clipboard where you want.
There are a couple of Python libraries using which you can extract data from PDFs. For example, you can use the PyPDF2 library for extracting text from PDFs where text is in a sequential or formatted manner i.e. in lines or forms. You can also extract tables in PDFs through the Camelot library.
You can use the module PyMuPDF. This outputs all images as .png files, but worked out of the box and is fast.
import fitz doc = fitz.open("file.pdf") for i in range(len(doc)): for img in doc.getPageImageList(i): xref = img[0] pix = fitz.Pixmap(doc, xref) if pix.n < 5: # this is GRAY or RGB pix.writePNG("p%s-%s.png" % (i, xref)) else: # CMYK: convert to RGB first pix1 = fitz.Pixmap(fitz.csRGB, pix) pix1.writePNG("p%s-%s.png" % (i, xref)) pix1 = None pix = None see here for more resources
