Hi, I am trying to increase contrast in an image in C++ using the Image::level function. Somehow, this always results in a black image. I have a greyscale 12 bit image with min/max value around 1800/3800. My code is pretty straight forward: image.level(m_minValue, m_maxValue); I expected this to "stretch" my image, so that the whole 16 bits are used. I tried to debug, and to me it seams that the white_point parameter is never used, it is set to 1.0. If I, inside the enhance.c LevelImage function, set the white_point variable to my max value during debugging, it works fine. I am using the latest version (6.3.7). Does anyone have a tip? Am I doing something wrong here, or is there a bug?
