Implementation of IIIF v3 API for zoomified image tiles of herbarium specimens at the Royal Botanic Garden Edinburgh
"Full" images are created for each layer of the zoomify tile pyramid on request by stitching the tiles together. This is inefficient and so the results are cached in a directory called 'cache'. The code makes no attempt to manage the size of this cache so a cron job will need to be added to clear it out from time to time.
