--- Comment #22 from Michael Miller <michael_mil...@msn.com> --- Hi Andy, Can you explain something please? How did you get the superpower to find bugs in code that has been working well for months. :) You found another well-hidden bug in digiKam. Maik/Gilles, The issue is the thumbnail QImage being returned from the thumbnail service is has a format of QImage::Format_RGB32. If I raw convert the QImage to an OpenCV cv::Mat, I should get a RGB cv::Mat image. What I get is actually BGR. YuNet and SFace want RGB format images, and not BGR. I don't know if this is adysfunction in the thumbnail service, but in other places when I convert a QImage to cv::Mat the color coding is correct. If I convert the thumbnail QImage to BGR, the result thumbnail is actually RGB, and is processed correctly. Andy, I also found out why you have run recognize twice. I'm fixing that, too. There should be a new build in a few days. Cheers, Mike -- You are receiving this mail because: You are watching all bug changes.
