DAKPANNENLATENVERVANGEN.NL — PHOTO SOFTWARE NOTICES

The HEIC/HEIF photo converter uses heic-to and its bundled libheif/libde265
implementation. The converter runs in the visitor's browser. The website
uses the heic-to/csp entry point and loads it when HEIC conversion is needed.

VERSION AND BUILD PROVENANCE

The installed heic-to 1.6.7 package's CSP decoder source begins with:
// Build from libheif 1.23.7 with USE_UNSAFE_EVAL=0 and LIBDE265_VERSION=1.0.16

That exact header, together with the package release table, identifies the
versions above. One sentence in the upstream README still says 1.23.6;
the 1.6.7 release table and bundled decoder header both say 1.23.7.
The package sources have not been locally modified. The website build
bundles the package for browser use. The upstream README describes the
Emscripten build commands, build-script adjustment and CSP build flags.

The original package and versioned native-library source archives above
are supplied without local changes. Consult their included licence files
for the full terms, permissions and warranty notices.
