FilePresto picture engine: exact build and source information
=============================================================

FilePresto (filepresto.com) uses ImageMagick compiled for the browser to open TIFF files, to pick frames from
animated GIF files and, when the browser itself cannot, to open unusual BMP files. It runs entirely on the
visitor's device. The files are served unchanged, exactly as published.

Files served by FilePresto:
  /assets/lib/magick/magick-engine.js  = dist/index.js from the package, unchanged.
  /assets/lib/magick/magick-wasm.bin   = dist/x86/magick.wasm from the package, unchanged, compressed with gzip
                                         for delivery and decompressed in the browser before use.
  /assets/lib/licences/magick-wasm-NOTICE.txt  = NOTICE from the package (licences of ImageMagick and the
                                         23 libraries it contains).
  /assets/lib/licences/magick-wasm-LICENSE.txt = LICENSE from the package (Apache License 2.0).

Libraries under the GNU Lesser General Public License
-----------------------------------------------------
The engine contains libde265, libheif, glib, liblqr and LibRaw, which are published under the GNU Lesser
General Public License (their licence texts are in the NOTICE file). Their complete corresponding source code,
and the scripts used to build and link them into the engine, are public at the Magick.Native link above, at
the exact tag used.

You may replace the engine with your own modified or relinked version. The engine is a separate file that the
page loads by name (magick-wasm.bin, gzip-compressed WebAssembly), and the page does nothing to prevent it being
replaced: for example, a browser's developer tools or a local override can serve a rebuilt magick.wasm in its
place.

Changes by FilePresto: none to the engine files. FilePresto's own code (/assets/tools/magick-worker.js) calls
the engine's published functions, and is not part of the engine.
