How to extract texts between two coordinates in a page?

[StephenZKCurry]

I want to extract texts between two coordinates on a page use the PDF's underlying flow of characters as a guide for ordering and segmenting the words, rather than presorting the characters by x/y position, mimics dragging a cursor highlights text in a PDF, How can I do that?

You can supply an arbitrary rectangle ("clip") inside which your desired text lives. If you only have top and bottom values, make a rectangle clip = pymupdf.Rect(0, top, page.rect.width, bottom).
Then execute text = page.get_text(sort=True, clip=clip).
This will (pymupdf v1.24.11+) extract the text in reading order.
