We assume that each color component, that is, alpha, red, blue, and green, is
represented using an 8-bit byte. We define the corresponding type as uint8. A
whole ARGB pixel is represented by a type called uint32, which is an unsigned
integer consisting of 32 bits. In the code showing the behavior of the
transforms, these values are codified in the following bits: alpha in bits
31..24, red in bits 23..16, green in bits 15..8 and blue in bits 7..0; however,
31..24, red in bits 23..16, green in bits 15..8, and blue in bits 7..0; however,
implementations of the format are free to use another representation internally.
