They also provide both a fully configured IIP URL endpoint as well as a ready-to-use clean IIIF Image API v3 endpoint.

The packages are based on updated versions of the original Debian builds and include all available features in an easy to install package. These packages are configured to provide full TIFF, JPEG2000 and JPEG input support as well as TIFF, PNG, WebP and AVIF output.

Multi-platform Docker images of the latest 1.3 release of iipsrv are also now available from Docker Hub. Images are only 18MB in size, fully configurable and provide a running instance of iipsrv with clean #IIIF URLs out of the box: https://t.co/FyRrlXvr7h

Version 1.3 of iipsrv, the IIPImage server, is now officially released and available for download. This is a major new version containing a whole host of new features, major performance enhancements, optimizations and numerous bug-fixes:

For Alpine Linux users, the "edge" repository has already updated to iipsrv version 1.3. Just upgrade with "apk upgrade" and install with: "apk add iipsrv".

[IIPImage @iipimage]

Major new features include optimized support for JPEG input images, output support for TIFF and AVIF formats, a new fast low latency pass-through mode, #IIIF enhancements, improved metadata support, build and packaging improvements and more.

@jyzg TIFF, of course does allow efficient rendering of regions. But does libjxl in fact allow region decoding? Unfortunately, it seems like it's not yet supported: https://t.co/a9cuvUAcro

A detailed look at TIFF compression options and how this choice affects both file size and especially decoding performance.

@jyzg But JPEG XL certainly looks like a promising format to replace standard JPEG. Whenever libtiff adds support for this, I'll update the performance tests

[IIPImage @iipimage]

@jyzg Thus, it is possible to apply JPEG XL compression to a TIFF or DNG file and JPEG XL is indeed now often used within the DNG format. Unfortunately, for the moment, libtiff does not support JPEG XL compression within TIFF ...

But most crucial for #IIIF and pan-and-zoom use is decoding speed. Here ZStandard performs particularly well for lossless compression. For lossy compression, WebP is slightly slower than JPEG, but not by much.
