libvips: fast, low-memory image processing library with command-line and many language bindings

What it supplies: libvips is a demand-driven, horizontally threaded image processing library. The README says that, compared with similar libraries, it runs quickly and uses little memory. It has around 300 operations covering arithmetic, histograms, convolution, morphology, frequency filtering, colour, resampling and statistics. Useful for: - Batch-process images from the command line, or from C, C++ and language bindings including Python, Ruby and Rust. - Read and write formats including JPEG, TIFF, PNG, WebP, HEIC and AVIF, and load others through ImageMagick. First action: - Install a package from your package manager, or take Windows binaries from the releases page. - To build from source, install Meson 0.56 or later, ninja or another backend, and the required development libraries. Prerequisites and limits: - Source builds use Meson 0.56 or later, plus build-essential, pkg-config, libglib2.0-dev and libexpat1-dev. - Text rendering needs pangocairo. - OpenEXR images can be read but not written. - Enabling ImageMagick support for untrusted images has security implications because of its large attack surface. The README states libvips is licensed under LGPL-2.1-or-later. Images you process carry their own rights. Written from the README text only. Statements are as the README gives them; nothing was installed or run and no benchmark was made, so the speed and memory claims are the README's own. Based on README text only; the linked benchmarks and licence file were not read. No install or run was made; speed and memory claims are the README's own.
