How to convert image from double to uint8 in MATLAB?

I — Input image scalar | vector | matrix | multidimensional array If I is a grayscale or truecolor (RGB) image, it can be uint8 , uint16, double , logical, single, or int16. If I is an indexed image, it can be uint8, uint16 , double or logical. If I is a binary image, it must be logical.
