libvips
libvips is an image-processing library built for demand-driven work across multiple threads, with low memory use. Its roughly 300 operations cover arithmetic, histograms, convolution, morphology, frequency filtering, colour, resampling and statistics. It handles formats including JPEG, JPEG 2000, JPEG XL, TIFF, PNG, WebP, HEIC, AVIF, FITS, Matlab, OpenEXR, PDF, SVG, GIF, DeepZoom and OpenSlide. Developers can use C, C++, command-line tools, or bindings for Ruby, Python, PHP,.NET, Go, Lua, Crystal, Elixir, Java and Nim. Packages are available for most Unix-like systems, and libvips can also be installed on macOS and Windows. Windows downloads include a web-focused build with a limited reader set and a larger build with all supported readers; the project advises care before publicly deploying the latter. Optional dependencies and build choices can be selected from source. Use cases include large images, many CPUs, colour work, scientific analysis and general research and development. Its official GUI is nip4, and the library is licensed under LGPL-2.1-or-later. The listed plan is free.
