some part of content has been left out

Example pdf:
动手学深度学习.pdf

The part of this page can't be parsed by pymupdf.

doc = fitz.open('xxx.pdf')
doc[27].get_text('dict')

All blocks are text type. Maybe this part is text, but its text info is also not included in blocks.

This is a "Discussions" item, so I first transfer it.

The objects inside the red rectangle are no text - nothing has been left out.
What you see there is vector graphics.
Confirm this by trying to mark anything inside that box using some PDF reader.

Can vector graphics be parsed by any API in pymupdf? How can I get it?

Look at the description of page.get_drawings(). This extracts vector graphics from the page.

Thanks a lot.
