As of 7.2, the canvas dimension options (iiif.canvas.default-width and iiif.canvas.default-height) are updated with additional behaviors. - If you do not provide your own default dimensions in
iiif.cfg, DSpace will attempt to optimize canvas dimensions when dimension metadata is missing from the first bitstream in the item. This will often produce more accurate viewer layouts, but note that it is not sufficient to assure accurate layouts in all cases. - If you decide to add your own default dimensions in
iiif.cfg file your dimensions are used for every bitstream that lacks dimension metadata. - You may also set both default dimensions in
iiif.cfg to the value -1. In this case, DSpace creates accurate default dimensions for every bitstream that lacks dimension metadata. Note that this impacts performance.
It is recommended that iiif.image.width and iiif.image.height metadata be added to Item, Bundle, or Bitstream metadata to assure accurate layout and top performance. Default dimension configurations are intended to improve the user experience when dimension metadata has not yet been added. |
