Integrate WIA (Windows Image Acquisition) into Qt project

moravas

Hi Folks,

I have to capture scanner image trough my Qt based application on Windows 7. As I saw, WIA would be the most Windows conform solution to do that, but it based on COM.
Can anybody help me, how can I compile COM based source via Qt project? Even more, does anybody have experience in WIA + Qt usage?

Regards,
Norbert

@moravas If it is COM then you can use http://doc.qt.io/qt-5.7/activeqt-container.html

Thank you very much!!! It seems to be a good starting point, but how can I compile IDL files? If you can check the link, it points to have a header and IDL file to.

Moreover, does anybody have experience in WIA?

Thanks, it seems to be nice. It sounds to me, that the IDL should be compiled before the regular C++ sources. What should I write into my .pro file to do that?

Hi,

There's an example here for IDL.
