Where is uint32

If you want an integer with the widest range possible on the platform on which it is being used, use one of the following.

If you use these, you should write code that takes into account the variable size and range of the integer. The GNU C Library also provides macros that tell you the maximum and minimum possible values for each integer data type. The type specifies a signed integer type large enough to support interconversion with a void pointer. The macros each convert an integer literal to an unsigned integer type whose representation has at least eight, 16, 32, or 64 bits, respectively.

The types each specify an unsigned integer type whose representation has exactly eight, 16, 32, or 64 bits, respectively. The types each specify an unsigned integer type that supports the fastest operations among those whose representation has at least eight, 16, 32, or 64 bits, respectively.

The image function can display 8- or bit images directly without converting them to double precision. How many bytes is a uint8? What is the difference between int and unsigned int? You may also refer to this data type as signed int or signed. What is uint8 in Python? OpenCV apparently expect array to be made of 8-bit tuples representing red, green and blue. On one machine, it might be 32 bits the minimum required by C. On another, it's 64 bits.
