encodeWS2816()

template<typename InputIterator, typename OutputIterator>

void fl::encodeWS2816	(	InputIterator	first,
		InputIterator	last,
		OutputIterator	out )

Encode 16-bit RGB pixel data into dual 8-bit RGB format for WS2816.

Template Parameters

InputIterator	Iterator yielding fl::array<u16, 3> (16-bit RGB in wire order)
OutputIterator	Output iterator accepting CRGB (e.g., raw pointer)

Parameters

first	Iterator to first pixel
last	Iterator past last pixel (sentinel)
out	Output iterator for encoded CRGB pairs

Note

Each input pixel yields 2 CRGB output pixels (48 bits → 2×24 bits)

Input iterator yields wire-ordered 16-bit RGB (reordering already done upstream)
