How do I write a RGB image with the function cv::imwrite()? So far all my attempts lead into writing a BGR image instead.
My matrix object is a cv::Mat.

The
cv::imwrite()function correctly writes an image file if the inputcv::Matis in BGR order (which is the case if you let OpenCV create it). If you created the image by yourself, you have to convert the color ordering before, for example by calling as suggested by bamboovecv::cvtColor(in, out, CV_RGB2BGR);if you created an RGB image.(Pay attention to the color conversion code, it’s slightly different from bamboon’s.)
