Dynamically loaded by sharp-win32-x64-0.35.5.node; both DLLs may be replaced with compatible modified builds. (1a) libvips-42.dll SHA-256: 06dab07cc386748513337a31672b1d5269fbc770a14ff403080575665bf0813f libvips 8.18.7 and the libraries listed below, compiled and statically linked into one DLL by the libvips project's Windows build system libvips/build-win64-mxe v8.18.7 (tag commit ef19ca09af2453d127453d677c849ccb37cf5694). That build uses the MXE cross-build environment kleisauke/mxe, branch llvm-mingw-20260924, which provides the package build recipes and patches; build-win64-mxe adds its own overrides and patches. The build records only the branch name, not a commit. The source set published for PicPrep pins the branch head commit c36160b231e66e1cbe032ed54aef7617e8b259da (its commits are dated 2026-09-24, before the build-win64-mxe v8.18.7 release on 2026-09-26); that this exact commit was used is not recorded by the build. librsvg's Rust code is compiled into the DLL together with the crates.io packages locked by librsvg 2.63.2's Cargo.lock, and the Rust standard library of the nightly toolchain of 2026-09-24 (built with -Zbuild-std; MIT / Apache-2.0). The DLL is byte-identical to bin/libvips-42.dll in the release asset vips-dev-x64-web-8.18.7-static.zip (SHA-256 a736af61d3b46499760efa606e469cb14e060445b1f6fd36a1fa2e75009e1197). sharp-libvips v1.3.4 repackages this release binary without rebuilding it (build/win.sh). (1b) libvips-cpp-8.18.7.dll libvips C++ binding: the unmodified files VConnection.cpp, VError.cpp, VImage.cpp (including vips-operators.cpp), VInterpolate.cpp and VRegion.cpp from the cplusplus/ directory of libvips 8.18.7, as distributed in the npm package @img/sharp-libvips-dev 1.3.4. Compiled by the sharp 0.35.5 build (src/binding.gyp, target libvips-cpp-8.18.7) and linked against libvips-42.dll.
