RTI & IIIF tiles-on-demand support ? #39

Open atiro opened 1 year ago

atiro commented 1 year ago

I wondered if it's planned to enable support for serving up RTI images using IIIF tiles-on-demand instead of whole images, or does that not work with the new way the RTI data is stored ? (Possibly it would need to request 3 tiles simultaneously ?)

If it is planned to do that, I wondered (longer-term) whether the data in the info.json might be something that could be integrated into the IIIF Image API as an extension, so a single info.json provides the information needs for both IIIF tile retrieval and RTI calculations.

Apologies if I've mis-understand the architecture, still getting my head round how it all works.

Openlime supports many different types of tiled images: deepzoom, zoomify, google and iiif.

Given the lack of rti standards and, moreover, lack of a rti standard for iiif, openlime follows relight json format. It is possible to use iiif served images, i just need to provide some documentation on how to do it and how to do it efficiently.

Ah thanks @ponchio, I had misunderstood a comment in the code and didn't think the relight images could be served up as tiled/zoom images. Docs would be really useful, thank you.

On the IIIF/RTI standard extension, perhaps that's something I can pick-up with you on email, if that would be of interest to pursue? We would be interested in supporting that.

Sure, I would love to see a standard IIIF manifest for RTIs, write me to ponchio@gmail.com, and we can arrange a call.
