process_to_container() [2/2]

std::shared_ptr< Kakshya::TextureCollection > MayaFlux::Yantra::Vision::VisionWorkflow::process_to_container ( const std::vector< std::shared_ptr< Core::VKImage > > &  frames, Kinesis::Vision::VisionQuery  query, VisionExtractMode  extract, Kakshya::TextureCollectionSpec  spec = {}  )

static

Run query over frames in order and record what extract takes from each into a collection.

Null frames, and frames whose extraction gives no image, add no layer. A width or height of zero in spec takes the first frame's; its byte cap and ring are not used.

Returns

The filled collection, or null when frames holds no image.
