More information

For an N-bit-per-component RGB frame buffer format, the lowest N bits must contain the blue component, the next N bits must contain the green component, the next N bits must contain the red component, and the remaining 32-(3 x N) bits may contain alpha. The resulting 32-bit value must be stored in memory in little-endian format.

Note

This requirement is "If-Implemented" for Windows Server.
