HEIC conversion

HEIC decoding uses heic-to 1.5.2 by Hopper Gee, libheif 1.22.2 and libde265 1.0.16. These libraries are covered by the GNU Lesser General Public License, version 3 or later where specified. You may modify these portions and reverse engineer the combined work to debug those modifications. The linked corresponding sources and application code allow rebuilding with modified versions.

• Rebuild, relink and distribution instructions
• Source origins and checksums

To relink: extract the application archive; rebuild the included heic-to sources, following its README and esbuild.mjs; install that compatible local library with npm install /path/to/modified-heic-to; then run npm run build using Node.js 24. For native decoder changes, the supplied source archives and libheif build script contain the upstream reconstruction instructions. No bit-for-bit reproducibility guarantee is made.
