--- Comment #15 from caulier.gil...@gmail.com --- TWAIN is perhaps deprecated under Windows, but it's a legacy digital Acquisition system which must work as expected. From wikipedia page, this one still maintained until now : https://en.wikipedia.org/wiki/TWAIN The advantage of Twain is the compilation one : it do not require an extra library from Microsoft. All is include in core. This is why we can cross compile whole DK with Twain support under Linux as well. This is a great advantage, because we won't to require Windows and MSVC to compile the whole DK bundle including Qt5, KF5, and all extra dependecies required. With a cross compiler open source as MXE, i just to press a button under Linux, and 2 hours later, the installer is ready to use under Windows. Magic. In other words, i won't to use M$ stuff to compile whole DK : it's just a waste of time. M$ is not a devel env for me, it's just a graphic console dedicated to run softwares. I'm my viewpoint, very negative about Windows, but it's the reality. I devel cross plateform softwares in my office, and Windows is THE computer puzzle for developers. So, from my side, There is no way to switch whole DK windows compilation in the future, and until the end of the world.
