to_image() [1/2]

std::shared_ptr< Core::VKImage > MayaFlux::Kakshya::WindowContainer::to_image

(

)

const

Upload the full surface readback to a container-owned VKImage.

Requires at least one completed readback (processed_data[0] non-empty and of type vector<uint8_t>). Reuses the image while dimensions and format match. The returned image is refreshed in place by later calls, so it is a live image rather than a snapshot.

Returns

Cached VKImage, or nullptr on failure.
