Hello David,
The software is designed to be as cross-platform as possible and
contains only small components that depend on MS Windows. I plan to add
Linux and macOS support in the future, but I just haven't had time for
that yet. I chose MS Windows as the supported operating system because
it has the most users and therefore potentially the most people
interested in my software. It would also be necessary to edit .pro files
that are only ready for MS Windows and implement platform dependent
issues, for example, font handling.
Currently, I am fully focused on preparing a program for comparing
similar pdf files so that it is comparable to commercial programs.
Detection of page or text movement will also be supported, including
visualization of changes in the window. This functionality is a bit
complex and I expect to be able to complete it sometime in November or
December.
Best regards,
Jakub Melka

Hi Jakub,
Thanks for sharing. This does look very interesting. Is there anything
in the code or dependencies that explicitly depends on Windows, or
could this in theory be compiled to macOS or linux with some
additional work?
Cheers,
David Skoland

Dear Qt users,
I would like to inform you about my project, PDF4QT. I began this
project in year 2018 as my private project, and now, I think, it is
ready to be released for public beta testing. Long term goal of this
project is to offer full support of PDF 2.0 specification as add-on
library for Qt. I know, that Qt offers its own PDF module, but, it
lacks many functionality. My project offers much more, as optional
content handling, signature verification, encryption support, form
filling, color management, annotations, text to speech,
optimalization, sensitive content redaction, page manipulation,
document merging and splitting and much more. Also, I offer several
applications, which use this library, such as document viewer/editor,
or command line tool.
I am aware, that some other projects also implements this
functionality, but they are very often using viral licenses such as
GPL/AGPL. I want to be more benevolent, so PDF4QT project uses LGPL
license, version 3, so it is usable also in commercial applications.
I do not want to restrict people from using my library.
Project can be found at this website:
https://github.com/JakubMelka/PDF4QT
<https://github.com/JakubMelka/PDF4QT>
And public beta release is available here:
https://github.com/JakubMelka/PDF4QT/releases
I hope you will find my 3-year work useful.
PS. I will be very happy if you can contribute in a form of testing,
advices, opinions... But I also want to keep control of the rights to
my project, so if you want to contribute, Contributor License
Agreement must be signed.
Please do not respond on my email, but if you want to discuss this
software, use following discussion forum:
