We are only volunteers spending spare time for the benefit of the community....
a few more abs shall be added:
line 773:

                font_height = abs(rct.height) - 2

line 776:

        y_offset = abs(rct.height) - 1 - font_height

Wow! Perfect. That worked. Thank you so much

[thusharagokulnath]

One thing I found about it is there is data on the field. It display data when I click on the field , it disappear just show the blue editable field when I move the cursor.

For me I am generating the PDF as readonly in above examples, there I cannot see the data at all

[pubpub-zz]

Your form is in readonly. Can you remove this restriction for analysis

[thusharagokulnath]

Sure. Please see the comment also

I've seen it but I would like to see how acrobat modifies the fields. In pdf.js the fields are visibles

[calixteman]

With pdf.js the values of the fields are correct because we use their V entry. But if you try to print the pdf then the indicated fields are empty, so it's likely an issue in the appearance stream of those annotations (Acrobat and Chrome use the AS).

Below is the editable pdf generated
FRA F 6180.55_2022-09-01_2022-09-30_2024-06-25_17-35-06.pdf

Looking forward for a solution asap. It is a blocker for my project deployment

Thanks

I've understood : the boxes ("/Rect") are upside down Rect[1] is greater than Rect[3]. Just checking but a fix/patch should be available soon

[thusharagokulnath]

Thank you

[pubpub-zz]

can you try to modify _writer.py line 879:

        for line_number, line in enumerate(txt.replace("\n", "\r").split("\r")):
            if line in sel:
                # may be improved but cannot find how to get fill working => replaced with lined box
                ap_stream += (
                    f"1 {y_offset - (line_number * abs(font_height) * 1.4) - 1} {abs(rct.width) - 2} {abs(font_height) + 2} re\n" #<------------
                    f"0.5 0.5 0.5 rg s\n{da}\n"
                ).encode()

[thusharagokulnath]

what need to be modified? I am new to python, just trying understand

[pubpub-zz]

start the python idle,
press alt+M
open "pypdf._writer.py"
press alt+G
goto line 879
it should starts with :
f"1 {y_offset -
replace it with

                    f"1 {y_offset - (line_number * abs(font_height) * 1.4) - 1} {abs(rct.width) - 2} {abs(font_height) + 2} re\n" #<---------

save file, rerun your script. check result

[thusharagokulnath]

Thank you.
This line of code is in line 843, so got confused.
Even though I tried changing it and rerun the script. but not worked. still the same

[pubpub-zz]

at line 839, you can find:
ap_stream = f"q\n(...)
replace it with

        ap_stream = f"q\n/Tx BMC \nq\n1 1 { abs(rct.width) - 1} {abs(rct.height) - 1} re\nW\nBT\n{da}\n".encode()

[thusharagokulnath]

Tried it. Still no luck

Thanks

Any update?

[thusharagokulnath]

Sorry for pushing . It is a blocker for my project.

[pubpub-zz]

any update ?

[thusharagokulnath]

No luck. Still same

[pubpub-zz]

working for me 🤔
can you send me your output file ?

[thusharagokulnath]

FRA F 6180.55_1.pdf

[pubpub-zz]

I think it should be good now : I missed the /BBox field
for line 745

        rct = RectangleObject((0, 0, abs(_rct[2] - _rct[0]), abs(_rct[3] - _rct[1])))

[pubpub-zz]

This should be part of next release
