blend_frames()

MAYAFLUX_API bool MayaFlux::Kakshya::blend_frames	(	ImageFormat	format,
		std::span< const uint8_t >	a,
		std::span< const uint8_t >	b,
		uint8_t *	out,
		double	weight
	)

Linearly blend two frames of the same size and format.

Works on 8-bit and 32-bit float storage. Returns false, leaving out untouched, for any other element size or when the frames differ in size.

Parameters

format	Pixel format of both frames.
a	Frame at weight 0.
b	Frame at weight 1.
out	Destination for a.size() bytes.
weight	Blend factor from a to b.

Returns

True if out holds the blend.
