Third-party notices

The Quire image tools at quireapps.com/image/ use the open-source components below. Each one is served from quireapps.com as its own file under vendor/, and loads only in a background worker when a tool needs it. Nothing is loaded from a CDN.

libheif and libde265 (HEIC decoding)

• Package: libheif-js 1.23.5 by Kiril Vatev, an Emscripten build of libheif. License: LGPL-3.0. Source: github.com/catdad-experiments/libheif-js, built from github.com/catdad-experiments/libheif-emscripten.
• libheif 1.23.5 by struktur AG. License: LGPL-3.0. Source: github.com/strukturag/libheif.
• libde265 1.0.15 (HEVC decoder) by struktur AG, compiled into the same WebAssembly file. License: LGPL-3.0. Source: github.com/strukturag/libde265.
• Files: vendor/libheif/libheif.mjs (91 KB) and vendor/libheif/libheif.wasm (1.46 MB).
• License texts: LICENSE-libheif-js.txt, LICENSE-libheif.txt, LICENSE-libde265.txt and the GNU GPL 3.0 text that the LGPL refers to, GPL-3.0.txt.

libheif.wasm is the file published in the libheif-js npm package, unchanged. libheif.mjs is the package's libheif-wasm/libheif.js, unchanged, with one line added at the end (export default libheif;) so that it can be imported by a module worker. The Quire code uses libheif only through its JavaScript interface and does not include or modify any libheif code. To use a different build of libheif, replace these two files with another libheif-js release of the same interface. The corresponding source code for this build is at the links above, at tag v1.23.5 of libheif-js and libheif and v1.0.15 of libde265.
