libvips is a 2D image processing library. Compared to similar libraries, libvips runs quickly and uses little memory.
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, FITS, Matlab, OpenEXR, and OpenSlide. It can also load images via ImageMagick or GraphicsMagick.
There's a GUI as well, see the VIPS website.
There are packages for most unix-like operating systems and binaries for Windows and OS X.
In the libvips directory you should just be able to do:
$ ./configure $ make $ sudo make install
By default this will install files to
See the Dependencies section below for a list of the things that libvips needs in order to be able to build.
Checkout the latest sources with:
$ git clone git://github.com/jcupitt/libvips.git
Then for a debug build:
$ ./bootstrap.sh $ CFLAGS="-g -Wall" CXXFLAGS="-g -Wall" \ ./configure --prefix=/home/john/vips --enable-gtk-doc $ make $ make install
$ export G_DEBUG=gc-friendly $ export G_SLICE=always-malloc $ valgrind --suppressions=libvips.supp \ --leak-check=yes \ vips ... > vips-vg.log 2>&1
valgrind threading check:
$ valgrind --tool=helgrind vips ... > vips-vg.log 2>&1
$ CC=clang CXX=clang++ ./configure --prefix=/home/john/vips
Clang static analysis:
$ scan-build ./configure --disable-introspection $ scan-build -o scan -v make $ scan-view scan/2013-11-22-2
Clang dynamic analysis:
$ FLAGS="-O1 -g -fsanitize=address" $ FLAGS="$FLAGS -fno-omit-frame-pointer -fno-optimize-sibling-calls" $ CC=clang CXX=clang++ LD=clang \ CFLAGS="$FLAGS" CXXFLAGS="$FLAGS" LDFLAGS=-fsanitize=address \ ./configure --prefix=/home/john/vips --disable-introspection $ FLAGS="-O1 -g -fsanitize=thread" $ FLAGS="$FLAGS -fPIC -pie" $ FLAGS="$FLAGS -fno-omit-frame-pointer -fno-optimize-sibling-calls" $ CC=clang CXX=clang++ LD=clang \ CFLAGS="$FLAGS" CXXFLAGS="$FLAGS" \ LDFLAGS="-fsanitize=thread -fPIC -pie" \ ./configure --prefix=/home/john/vips --disable-introspection
Build with the GCC auto-vectorizer and diagnostics (or just -O3):
$ FLAGS="-O2 -msse4.2 -ffast-math" $ FLAGS="$FLAGS -ftree-vectorize -fdump-tree-vect-details" $ CFLAGS="$FLAGS" CXXFLAGS="$FLAGS" \ ./configure --prefix=/home/john/vips --disable-introspection \ --enable-debug=no
Static analysis with:
$ cppcheck --force --enable=style . &> cppcheck.log
libvips has to have gettext, glib-2.x and libxml-2.0. The build system needs sh, pkg-config, swig, gtk-doc-tools, automake, gobject-introspection and gnu make.
If suitable versions are found, libvips will add support for the following
libraries automatically. See
./configure --help for a set of flags to
control library detection. Packages are generally found with
so make sure that is working.
libtiff and libjpeg do not usually use pkg-config so libvips looks for them in the default path and in $prefix. If you have installed your own versions of these libraries in a different location, libvips will not see them. Use switches to libvips configure like:
./configure --prefix=/Users/john/vips \ --with-tiff-includes=/opt/local/include \ --with-tiff-libraries=/opt/local/lib \ --with-jpeg-includes=/opt/local/include \ --with-jpeg-libraries=/opt/local/lib
CFLAGS="-g -Wall -I/opt/local/include -L/opt/local/lib" \ CXXFLAGS="-g -Wall -I/opt/local/include -L/opt/local/lib" \ ./configure --without-python --prefix=/Users/john/vips
to get libvips to see your builds.
The IJG JPEG library.
If available, libvips adds support for EXIF metadata in JPEG files.
The TIFF library. It needs to be built with support for JPEG and ZIP compression. 3.4b037 and later are known to be OK.
If your TIFF library includes ZIP compression, you'll need this too.
If libvips finds this library, it uses it for fourier transforms. It can also use fftw2, but 3 is faster and more accurate.
If present, im_icc_import(), _export() and _transform() are available for transforming images with ICC profiles. If lcms2 is available, it is used in preference to lcms since it is faster.
libvips uses the standard autoconf tests to work out how to support large files (>2GB) on your system. Any reasonably recent *nix should be OK.
If present, libvips can load and save png files.
if available, libvips adds support for loading all libMagick supported
image file types (about 80 different formats). Use
--with-magickpackage to build against graphicsmagick instead.
If available, libvips adds support for text rendering. You need the
package pangoft2 in
If available, vips will accelerate some operations with this run-time compiler.
If available, vips can load images from Matlab save files.
If available, vips can load FITS images.
If available, libvips will directly read (but not write, sadly) OpenEXR images.
If available, libvips can load OpenSlide-supported virtual slide files: Aperio, Hamamatsu, Leica, MIRAX, Sakura, Trestle, and Ventana.
If available, we build the python binding too.
