template<class T >

Image<PixRGB<T> > fromRGB	(	const T *	data,
		const size_t	length,
		const Dims &	dims,
		const bool	byteswap
	)			[inline]

Build an RGB image from an RGB C array, with optional byte-swapping.

If byte-swapping is off, this will just perform a deep copy of the data; this function is somewhat redundant with the Image constructor and is provided for completeness with respect to the fromXXX methods only. Note that data should have 3*dims.w()*dims.h() elements, and it is the responsibility of the caller to free that data later.
