libavif
Library for encoding and decoding .avif files
libavif is a portable, open-source C library that implements encoding and decoding for the AVIF (AV1 Image File Format), offering a robust, production-ready way to work with AVIF images across platforms. It supports all AV1-supported YUV formats and bit-depths, including alpha (transparency), and includes command-line tools (avifenc and avifdec) to easily convert to/from AVIF from common image formats like JPEG, PNG, or Y4M. The API is straightforward, allowing applications to integrate AVIF support natively — creating, decoding, compressing, or decompressing images programmatically. Recent developments have added experimental support for HDR gain maps, improved color-space handling (including wide color gamut and high bit depth), and better quality tuning modes for encoding, making libavif a cutting-edge tool for high-quality image compression. -

AV1 AVIF
AV1 Image File Format Specification - ISO-BMFF/HEIF derivative
...The project outlines the syntax and semantics required for AVIF compliance, including support for multiple image profiles, color depths, chroma subsampling modes, HDR/WCG, alpha channels, animation/image sequences, and various color-space/bit-depth combinations — making AVIF a versatile, modern image format suitable for both simple photos and advanced imagery needing high fidelity. The specification ensures interoperability across encoders and decoders, providing guidelines so that images created by any compliant AVIF encoder can be reliably decoded by compliant decoders. ... -

sharp
High performance Node.js image processing module
...Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips. Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available. Most modern macOS, Windows and Linux systems running Node.js v10+ do not require any additional install or runtime dependencies. ... -

flag-icons
A curated collection of all country flags in SVG
A curated collection of all country flags in SVG, plus the CSS for easier integration. For using the flags inline with text add the classes .fi and .fi-xx (where xx is the ISO 3166-1-alpha-2 code of a country) to an empty <span>. If you want to have a squared version flag then add the class fis as well. You could also apply this to any element, but in that case you'll have to use the fib instead of fi and you're set. This means that the flag is just going to appear in the middle of an element, so you will have to set manually the correct size of 4 by 3 ratio or if it's squared add also the flag-icon-squared class. ... -

EpsEngine
Enables Qt based applications to export graphics to EPS format.
Starting with Qt 5, the possibility to export graphics to PostScript from Qt based applications was dropped: the QPrinter::PostScriptFormat option was removed. EpsEngine was developped in order to cover this lack and to enable Qt based applications to easily export graphics to the Encapsulated PostScript format.
