Extract images from PDF without resampling, in python?

Question

How can I obtain all images from a pdf document, at native resolution and format? Basically, I want to extract tiff as tiff, jpeg as jpeg, etc., and without doing the resampling. The layout is not important to me.

In that case, you can simply use the module PyMuPDF in Python. This module will yield all images as .png files. Kindly refer to the below code:

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
