HEIC decoding
When your browser cannot open a HEIC file by itself, FolderPix loads a decoder on your device: heic-to version 1.6.7, built on libheif and libde265.
These libraries are free software, distributed under the GNU Lesser General Public License version 3. You can read the license notice as shipped, the LGPL v3 and the GPL v3. Their source code is available at the links above.
The decoder is delivered as its own separate file and has not been modified, so it can be replaced by a modified version. To receive a copy of the source code for the exact version used, write to contact.miraggia@gmail.com.
