Instance Method Details

#ability ⇒ Object

The three methods below are defined directly on DisplayImagePresenter in recent Hyrax. We keep them here as fallbacks for older Hyrax versions via ‘super rescue NoMethodError`:

- Recent Hyrax: super succeeds silently, no deprecation noise.
- Older Hyrax:  super raises NoMethodError, deprecation fires, fallback value returned.

These fallbacks will be removed in the next major version of iiif_print.
