Except for page 7 (0-based), none of the pages contains an image.
What you see are vector graphics - no images.

[JorjMcKie]

Vector graphics cannot be extracted. All you can do is making a "photo" of the respective page area ...

[bbfrog]

Acrobat API can extract the vector graphics and save as png or svg. How does it do this? Is it hard to support in Pymupdf? THanks!

[JorjMcKie]

You can try this script. Or do this:

import pymupdf

doc = pymupdf.open("input.pdf")
for page in doc:
    for i, bbox in enumerate(page.cluster_drawings()):
        pix = page.get_pixmap(clip=bbox, dpi=150)
        pix.save(f"{doc.name}-{page.number}-{i}.png")

Thanks @JorjMcKie very much. It works and can extract the image I want. But it also extracted tables from this pdf as drawing, is there any field can differentiate the tables with other drawing? Thanks!
