GNOME's Glycin Lands "Dramatically Improved" JPEG-XL Image Loading Performance

Written by Michael Larabel in GNOME on 22 August 2025 at 08:33 PM EDT. 4 Comments
Glycin 2.0 Beta 3 was released this week for the GNOME project providing a Rust-based library for decoding, editing, and creating images and associated metadata. Glycin is in turn used by a growing number of GNOME components for imaging needs.

Glycin 2.0 Beta 3 was released earlier today as a nice step up for the project ahead of next month's GNOME 49 release. The Rust-written Glycin image loading and editing code has "dramatically improved" its JPEG-XL image loading speed with Glycin 2.0 Beta 3. There are also Glycin bug fixes and other enhancements in this new test release.

The faster JPEG-XL loading comes from not using the image-rs feature to convert texture data to avoid an extra copy of the data.
