Out-of-order coordinates

[zhangtingyun]

I just simply called the method in pdfminer to parse a pdf, but there is a problem with the coordinates of the parsed result, which is different from what I expected, sometimes the coordinates will be high, sometimes it will be low，but pdfJs can solve this problem I've made some modifications that fix this Tm_mul_CTM = matrix Th = scaling Tfs = fontsize _render_matrix = (Tfs * Th, 0,  # 0                   0, Tfs,  # 0                   0, rise  # 1                   ) Trm = mult_matrix(_render_matrix, Tm_mul_CTM) (a, b, c, d, e, f) = Trm w, h = x1 - x0, y1 - y0 (x0, y0) = (e, f) (x1, y1) = (x0 + w, y0 + h) y0, y1 = y0 + descent, y1 + descent

I don't know if my change is correct, please let me know or can you fix this bug, thanks!

Hi, I'm also facing the same issue while using pdfplumber which is developed base on pdfminer.six. In my usage, the pdfminer.six version is 20221105, pdfplumber version is 0.10.4 Even though I've tried repaired PDFs with ghostscripts, the as follow:

gswin64c -o repaired.pdf -sDEVICE=pdfwrite input.pdf 

output file is repaired.pdf Reference : https://github.com/jsvine/pdfplumber/issues/425

The repaired.pdf is still out of order while extracting text.

And I tried to remove * fontsize in descent The result goes correct

Is this a bug or something? Thanks
