Small update to #Annotorious, my #JavaScript image annotation library: You can now rotate rectangle shapes!

Quick question to the Fediverse: has anyone successfully implemented image embedding in the browser *with WebGPU support*?

All my attempts seem to fail. Regardless of wether im using Transformers.js or onnxruntime-web, pre-built models or ONNX files exported myself – at runtime, processing always seems to fall back to CPU.

(Interestingly: segmentation with a self-exported FastSAM model runs fine and *does* use WebGPU.)

Small update for tiny.iiif — my no-nonsense open-source IIIF server.

You can now choose your image server during setup:

• IIPImage
• Cantaloupe

(Big thanks to @atomotic for figuring out the IIPImage setup!)

For most use cases, it’s largely a matter of taste. In my experience, IIPImage tends to be slightly faster and a bit less resource-hungry, though.

Running small to mid-sized collections? Teaching with your own IIIF materials? Building IIIF-enabled tools? Check out tiny.iiif at:

It is done! 🚀 Today I’m publishing the first full, formal open source release of liiive — my web-based, real-time collaborative annotation environment for #IIIF image collections.

liiive enables users to view and annotate IIIF images together in real time — with shared cursors, synchronized drawing tools, and exportable, standards-compatible annotations.

As of today, the repository contains everything you need to run your own fully self-hosted instance:

https://github.com/rsimon/liiive

A big thank you to the University of Graz Department of Digital Humanities and the DHInfra.at initiative — this release wouldn’t have been possible without their support.

And now? it’s up to you!

Clone the repo. Deploy your own instance. Start annotating.

Most importantly: tell us how it goes. If something breaks, open an issue on GitHub. If something feels unclear, confusing, or slow — we want to know. Your feedback will shape where liiive goes next.

Yay! The first image served from my new tiny.iiif test instance.

I'm running on a 2 CPU/4GB RAM VM, which seems to be the absolute minimum, but performance is pretty slow.

If anyone has advice on what specs I'd need for getting more #IIIF speed out of Cantaloupe – let me know.
