@raven-worx do you know of any project to "Qt-ize" the interface?

Currently they use their own String class, which makes working with it difficult

Ok.
I have found a solution

QImage imageToReturn = QImage((uchar*)converted_image.data, converted_image.cols, converted_image.rows, QImage::Format_RGB888); imageToReturn.convertToFormat(QImage::Format_RGB32);

I have found that when i started to compare metadata between QImage constructed from cv::Mat data and QImage constructed as in second example

It worked! I had done it before but it was adding to the errors, and when I solved those I forgot to re add that. Thanks!
