Topic: Python script for generate cross-references in .pdf file

Hello everybody!

In the company where I work, Faramax, we have created (with the help of AI, because we are not code programmers), this program in Phyton to create links between references in a .pdf file
This is a stopgap while the integrated function in QET is being developed, which would be great. Wish we could help with this, but as I said we are not programmers.
We have based it on this, but I prefer to create a new topic so we don't mix up the posts: https://qelectrotech.org/forum/viewtopic.php?id=2915

This program have calibration and adjustment options. It does not acquire the positions of the QET elements, but creates a virtual grid that must be adjusted with the row, column and px values that it adjusts in the QET sheets.
Alse, the program have additional offset settings for fine tuning.

When the program finds a relation to the selected structure, it creates a link to the target page and grid position, with the selected settings and zoom.

Attached you can find the programme in .py and in a ready for windows .exe inside the .rar

Hopefully this tool will be useful to many people, until QET integrates the function to include the links in the exported pdf.

I would also like to thank the developers of this fantastic tool that helps a lot of people.

BR,
Alfonso.

Re: Python script for generate cross-references in .pdf file

I have tested the tool
I changed the settings to comply to my pages format

the tool finds 99 links but only 4 links created
they are on page 50

but the links are not going to the correct page
so what is the trick to make it working?

Re: Python script for generate cross-references in .pdf file

Hi LivenC,
The program looks for the texts with the format you set in the configuration (reference format) and creates a link to the corresponding page and zone of the .pdf
Your file has 20 sheets, so it is impossible to create links on sheet 50 for example.
I understand that in an electrical diagram the number of the printing sheet does not have to correspond to the name of the page, but this is not currently supported by the program.

I agree! And the best thing would be to include this functionality directly in QET built-in export tool.
We have little time to develop this tool.
Anyone can use the .py code and modify/improve it, if progress is made, please post it!

@Kellermorph: have you tried this python program on Linux, or make an AppImage?

No, how do you use to build python program in an AppImage?

I tried nuitka and pyinstaller with no luck.

I can build the AppImage in many VMs and they works well, but they don't work on other machines anymore.....

Re: Python script for generate cross-references in .pdf file

i didnt know the Modul. It seems its not integrated.

if u look into my .sh file.

at point 4 he copy the venv. thats where the python moduls are. That has to be copyed too.

maybe the problem is because u did:

pip uninstall fitz
pip install --upgrade --force-reinstall pymupdf

and its not integrated it the venv.

Maybe take a look at my update
https://qelectrotech.org/forum/viewtopic.php?id=2938

there is the complete Code with the .sh and maybe its easyer to see how it works.

Same things, if you can try, I give up!!
It's a shame we can't share it here for Linux users.

Re: Python script for generate cross-references in .pdf file

The app image is attached. I could not upload the folder structure and the .sh file to create an appimage because it is too big (262MB)
Unfortunately I could not test the function because my format of cross-references is not supported.
I am using Y.X. (page.column)
Alfonso could you add this function?
