upload_image()

bool MayaFlux::Kakshya::TextureContainer::upload_image	(	const std::shared_ptr< Core::VKImage > &	image,
		uint32_t	layer,
		const std::shared_ptr< Buffers::VKBuffer > &	staging
	)		const

Upload one layer into an existing VKImage instead of creating one.

Use this for an image retained separately from the container, such as an execution context's input image.

Parameters

image	Target image. Must match this container's width, height and format, and be a single layer 2D image.
layer	Array layer index (default 0).
staging	Host-visible staging VKBuffer sized to at least byte_size().

Returns

True when the layer was uploaded, false when the layer is out of range, empty, or the image is null.
