OpenCV JPEG 12-bit support - OpenCV Q&A Forum

    https://answers.opencv.org/question/1250/opencv-jpeg-12-bit-support/
    I am working on a project that requires processing grayscale JPEG images with 12-bit depth per pixel. Does OpenCV support 12-bit JPEG images? The 3rd party library 'libjepg' used by OpenCV supports 12-bit JPEG's but needs to be built for 12-bit support. The macro that defines 8/12-bit support is BITS_IN_JSAMPLE in jmorecfg.h under opencv/3rdparty/libjepg.
