submit_layer() [3/3]

bool MayaFlux::Buffers::TextureArrayBuffer::submit_layer	(	uint32_t	layer,
		std::span< const uint8_t >	pixels
	)

Replace the frame of one layer with raw pixels.

Parameters

layer	Layer index.
pixels	Exactly get_layer_byte_size() bytes.

Returns

True if the frame was stored.
