tg VS gImageReader

Their Desktop app is written in Qt C++[1].

This one is made with Qt: https://github.com/telegramdesktop/tdesktop I remembered this one.

But having checked clients for other platforms they are not made with Qt. You can check them all here: https://telegram.org/apps

p.s. i am also considering using c++, to try writing an extension of the source that implements the feature in a certain way, could you advise on how complex would this been?

In secret chat, you can't take any screenshot which can't be happened if it's implemented on Desktop app. That's the reason Telegram hasn't implemented the feature on its desktop versions. But that notification thing should be considered I guess… Someone should open an issue regrading it on it's GitHub repo.

On tesseract base here is a software to make a scan a text searchable pdf. It take a bit of time and can be a bit tedious but it does the work! https://github.com/manisandro/gImageReader/releases It does not work well on cursive writing of course. It's a bit less heavy code sided solution. Good luck!

I'm working with old newspaper PDFs to convert them into DOC formats. I'm having a great time with gImageReader by highlighting columns and converting them to plain text. Then I take that plain text into Libreoffice Writer (7.0.4.2) to clean up and save. If this were a book as opposed to a newspaper with ads and columns, it would have bee a lot easier to convert and format.

It would help to know a bit more of your usecase. If you're looking to just extract the text (ie, take all the textual content of your PDF and drop it into a separate text document), there are solutions like ABBYY Finereader and gImageReader. If you're looking to make PDFs searchable (keeping the scanned pages, but adding a text layer underneath so you can search and copy from them), there's NAPS2 (which has an additional command line tool for automation) and OCRmyPDF.

OpenSource OCR... for desktop users I like "gImageReader" URL: https://github.com/manisandro/gImageReader (Technically is GUI for tessaract)

gImageReader is the linux standard that I'm aware of. It's a GUI to Tessaeract, but IIRC you can use other models if you have them.

gImageReader as a simple OCR application

https://github.com/manisandro/gImageReader ^^ seems like it has installers for different OS's
