+libvips : an image processing library
+ +
+
libvips is a 2D 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, +convolutions, 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. It supports a good range of +image formats, including JPEG, TIFF, PNG, WebP, FITS, Matlab, OpenEXR, +PDF, SVG, HDR, PPM, CSV, GIF, Analyze, DeepZoom, and OpenSlide. It can +also load images via ImageMagick or GraphicsMagick.
+ +It has APIs for +C +and +C++ +and comes with a Python +binding +and a command-line +interface. +Bindings are available for Ruby, +JavaScript and others. There is full +documentation. +There are several GUIs as well, see the VIPS +website.
+ +There are packages for most unix-like operating systems and binaries for +Windows and OS X.
+ +Building libvips from a source tarball + +We keep pre-baked tarballs of releases on the vips website:
+ +http://www.vips.ecs.soton.ac.uk/supported/current/
+ +Untar, then in the libvips directory you should just be able to do:
+ +$ ./configure
+Check the summary at the end of configure carefully.
+libvips must have build-essential, pkg-config, glib2.0-dev, and
+libxml2-dev.
For the vips8 Python binding, you must have
+gobject-introspection, python-gi-dev, and libgirepository1.0-dev.
You'll need the dev packages for the file format support you
+want. For basic jpeg and tiff support, you'll need libtiff5-dev,
+libjpeg-turbo8-dev, and libgsf-1-dev. See the Dependencies section
+below for a full list of the things that libvips can be configured to use.
Once configure is looking OK, compile and install with the usual:
$ make
+$ sudo make install
+By default this will install files to /usr/local.
We have detailed guides on the wiki for building on +Windows +and building on OS +X.
+ ++Building libvips from git
+ +Checkout the latest sources with:
+ +$ git clone git://github.com/jcupitt/libvips.git
+Building from git needs more packages, you'll need at least swig, gtk-doc
+and gobject-introspection, see the dependencies section below. For example:
$ brew install gtk-doc swig
+Then build the build system with:
+ +$ ./bootstrap.sh
