Usage of uint16_t #37

Closed versatran01 closed 8 years ago

versatran01 commented 9 years ago

Is there any particular reason for using uint16_t instead of just unsigned? e.g. bool PointGreyCamera::setWhiteBalance(uint16_t &blue, uint16_t &red)

mikepurvis commented 8 years ago

No particular reason, but note that the blue and red values get bit-shifted into a single 32-bit register, so there'd be nothing gained from them being larger types.
