|

|
||||
<p>libvips is a 2D image processing library. Compared to
|
||||
similar libraries, <a href="http://www.vips.ecs.soton.ac.uk/index.php?title=Speed_and_Memory_Use">libvips runs quickly and uses little
|
||||
memory</a>.
|
||||
libvips is licensed under the LGPL 2.1+.</p>
|
||||
|
||||
<p>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.</p>
|
||||
|
||||
<p>It has APIs for
|
||||
<a href="http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/using-from-c.html">C</a>
|
||||
and
|
||||
<a href="http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/using-from-cpp.html">C++</a>
|
||||
and comes with a <a href="http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/using-from-python.html">Python
|
||||
binding</a>
|
||||
and a <a href="http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/using-cli.html">command-line
|
||||
interface</a>.
|
||||
Bindings are available for <a href="https://rubygems.org/gems/ruby-vips">Ruby</a>,
|
||||
JavaScript and others. There is full
|
||||
<a href="http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/index.html">documentation</a>.
|
||||
There are several GUIs as well, see the <a href="http://www.vips.ecs.soton.ac.uk">VIPS
|
||||
website</a>.</p>
|
||||
|
||||
<p>There are packages for most unix-like operating systems and binaries for
|
||||
Windows and OS X.</p>

|
||||
|
||||
<p>We keep pre-baked tarballs of releases on the vips website:</p>
|
||||
|
||||
<p><a href="http://www.vips.ecs.soton.ac.uk/supported/current/">http://www.vips.ecs.soton.ac.uk/supported/current/</a></p>
|
||||
|
||||
<p>Untar, then in the libvips directory you should just be able to do:</p>
|
||||
|
||||
<pre><code>$ ./configure
|
||||
</code></pre>
|
||||
|
||||
<p>Check the summary at the end of <code>configure</code> carefully.
|
||||
libvips must have <code>build-essential</code>, <code>pkg-config</code>, <code>glib2.0-dev</code>, and
|
||||
<code>libxml2-dev</code>. </p>
|
||||
|
||||
<p>For the vips8 Python binding, you must have
|
||||
<code>gobject-introspection</code>, <code>python-gi-dev</code>, and <code>libgirepository1.0-dev</code>.</p>
|
||||
|
||||
<p>You'll need the dev packages for the file format support you
|
||||
want. For basic jpeg and tiff support, you'll need <code>libtiff5-dev</code>,
|
||||
<code>libjpeg-turbo8-dev</code>, and <code>libgsf-1-dev</code>. See the <strong>Dependencies</strong> section
|
||||
below for a full list of the things that libvips can be configured to use.</p>
|
||||
|
||||
<p>Once <code>configure</code> is looking OK, compile and install with the usual:</p>
|
||||
|
||||
<pre><code>$ make
|
||||
$ sudo make install
|
||||
</code></pre>
|
||||
|
||||
<p>By default this will install files to <code>/usr/local</code>.</p>
|
||||
|
||||
<p>We have detailed guides on the wiki for <a href="http://www.vips.ecs.soton.ac.uk/index.php?title=Build_on_windows">building on
|
||||
Windows</a>
|
||||
and <a href="http://www.vips.ecs.soton.ac.uk/index.php?title=Build_on_OS_X">building on OS

|
||||
|
||||
<p>Checkout the latest sources with:</p>
|
||||
|
||||
<pre><code>$ git clone git://github.com/jcupitt/libvips.git
|
||||
</code></pre>
|
||||
|
||||
<p>Building from git needs more packages, you'll need at least <code>swig</code>, <code>gtk-doc</code>
|
||||
and <code>gobject-introspection</code>, see the dependencies section below. For example:</p>
|
||||
|
||||
<pre><code>$ brew install gtk-doc swig
|
||||
</code></pre>
|
||||
|
||||
<p>Then build the build system with:</p>
|
||||
|
||||
<pre><code>$ ./bootstrap.sh
|
||||
</code></pre>
