Detailed description

PNG format starts to support EXIF information since 2017, but somehow using IMREAD_COLOR to read a PNG file does not respect the orientation

Attached Capture.png and Capture.jpg are two images both with same EXIF orientation information, try both and you can see the difference.

Steps to reproduce

    // C++ code example
    cv::Mat cvImgColor = cv::imread("Capture.png", cv::IMREAD_COLOR);
    // Expected: cols = 333, rows = 280
    // Actual: cols = 280, rows = 333
