submit_layer() [1/3]

bool MayaFlux::Buffers::TextureArrayBuffer::submit_layer	(	uint32_t	layer,
		const Kakshya::ImageData &	image
	)

Replace the frame of one layer with an image.

An image of the layer's extent and format is stored as raw pixels. Any other is uploaded and fitted, or dropped when set_fit chose nullopt.

Returns

True if the frame was stored.
