encodeUCS7604_16bit_RGBW()

template<typename InputIterator, typename OutputIterator>

void fl::encodeUCS7604_16bit_RGBW	(	InputIterator	first,
		InputIterator	last,
		OutputIterator	out,
		const Gamma8 &	gamma )

Encode RGBW pixels in UCS7604 16-bit format with gamma correction.

Template Parameters

InputIterator	Iterator yielding fl::array<uint8_t, 4> (RGBW bytes)
OutputIterator	Output iterator accepting uint8_t

Parameters

first	Beginning of pixel range
last	End of pixel range
out	Output iterator for encoded bytes
gamma	Gamma8 LUT for 8-to-16 bit expansion

Note

Writes 8 bytes per pixel (R16_hi, R16_lo, G16_hi, G16_lo, B16_hi, B16_lo, W16_hi, W16_lo)
