libvips is a demand-driven, horizontally threaded image processing library. Compared to similar libraries, libvips runs quickly and uses little memory. libvips is licensed under the LGPL 2.1+.
It has around 300 operations covering arithmetic, histograms, convolution, morphological operations, frequency filtering, colour, resampling, statistics and others. It supports a large range of numeric formats, from 8-bit int to 128-bit complex. Images can have any number of bands. It supports a good range of image formats, including JPEG, TIFF, PNG, WebP, FITS, Matlab, OpenEXR, PDF, SVG, HDR, PPM, CSV, GIF, Analyze, NIfTI, DeepZoom, and OpenSlide. It can also load images via ImageMagick or GraphicsMagick, letting it load formats like DICOM.
It comes with bindings for C, C++, and the command-line. Full bindings are available for Ruby, Python, PHP, .NET, Go, and Lua. libvips is used as an image processing engine by sharp (on node.js), bimg, sharp for Go, Ruby on Rails, carrierwave-vips, mediawiki, PhotoFlow and others. The official libvips GUI is nip2, a strange combination of a spreadsheet and an photo editor.
The download area has the source code plus pre-compiled binaries for Windows; you can install on macOS with homebrew, MacPorts or Fink; and it’s available in most Linux package managers. See the install notes.

Thanks to work by Oscar Mira (@omira-sch), libvips has been in OSS Fuzz for about three weeks. I’m very happy to be able to report that only one real bug has been found so far, and none in the last five days.

I gave a 15m introduction to vips talk at LGM 2016, and just came across the video. It might be interesting.

libvips 8.7 is finally done!

There’s a new full libvips binding for .NET. It has a test-suite which passes with no memory leaks, it’s in
NuGet, so it’s easy to install on Linux, macOS and Windows, and it has nice documentation:

There’s a new major release of
ruby-vips, the Ruby binding for libvips: it’s now version 2.0. It has the same API (it passes the same test suite), but it’s simpler to install, works on Linux, macOS and Windows, it works with any Ruby (including JRuby), it’s smaller, more stable, and faster.

There’s a new libvips binding for Python. It has the same API as the one that comes with libvips (it passes the same test suite), it’s very easy to install on Linux, macOS and Windows, it works with any Python, it should be smaller and more stable, and it has nice new documentation:

LuaJIT now has a full libvips binding. It’s the whole of libvips, it has a test-suite which passes with no memory leaks, and it’s in
luarocksso it’s easy to install.

We have a new website running from github pages. Hopefully this will be easier to use and less work to maintain.
