WitrynaBy default, zmin and zmax correspond to the min and max values of the datatype for integer datatypes (ie [0-255] for uint8 images, [0, 65535] for uint16 images, etc.). For a multichannel image of floats, the max of the image is computed and zmax is the smallest power of 256 (1, 255, 65535) greater than this max value, with a 5% tolerance.
