libvips and its dependencies cross-compiled for all four Windows architectures (x86_64, i686, aarch64 and armv7).

Uses MXE as base environment. A custom plugin based upon the llvm-mingw repository is used to swap GCC and binutils with Clang and other LLVM-based tools.

Most people will not need to do this; proceed with caution.

Run the top-level build script with the --help parameter for help.

¹ A fork of the BSD 2-Clause licensed libimagequant v2.4.1 is used.

Same as libvips-web + these extra dependencies:

libvips does not use any of MozJPEG's improvements by default unless explicitly set, yet one can still choose to build the above variants with libjpeg-turbo instead of MozJPEG. This can be accomplished with the --with-jpeg-turbo argument. For example:

./build.sh --with-jpeg-turbo

In that case, the following version of libjpeg-turbo is built:

jpegli is an improved JPEG encoder and decoder implementation, fully compatible with the API/ABI of libjpeg62. It leverages many of the insights from related projects like guetzli, butteraugli, and JPEG XL to achieve a higher quality-per-byte for JPEG images. To enable this, use the --with-jpegli argument when building. For example:

./build.sh --with-jpegli

In that case, the following version of jpegli is built:

By default zlib-ng is built. This is a zlib replacement with optimizations for "next generation" systems. You can use the --without-zlib-ng argument during the build when (vanilla-)zlib is preferred. For example:

./build.sh --without-zlib-ng

In that case, the following version of zlib is built:

The above "all" variant can optionally be built with libde265 and x265 to process HEIC images. This can be turned on with the --with-hevc argument. For example:

./build.sh all --with-hevc

These dependencies include HEVC-related logic and are therefore not included in the prebuilt binaries while it is patent-encumbered.
