ark::image::ThumbnailGenerationStage

Defined in header “ark/image/stages/thumbnail_generation_stage.hh”.

This stage will receive camera images on a particular channel (via configuration), and then write out to disk a single thumbnail. It does this by waiting for a fixed number of frames to be received if it doesn’t get to that number by shutdown time, it will write out the most recent image.
