Installation

Wand itself can be installed from PyPI using pip:

$ pip install Wand

Wand is a Python binding of ImageMagick, so you have to install it as well:

Or you can simply install Wand and its entire dependencies using the package manager of your system (it’s way convenient but the version might be outdated):

Install ImageMagick on Debian/Ubuntu

If you’re using Linux distributions based on Debian like Ubuntu, it can be easily installed using APT:

$ sudo apt-get install libmagickwand-dev

If you need SVG, WMF, OpenEXR, DjVu, and Graphviz support you have to install libmagickcore5-extra as well:

$ sudo apt-get install libmagickcore5-extra

Install ImageMagick on Fedora/CentOS

If you’re using Linux distributions based on Redhat like Fedora or CentOS, it can be installed using Yum:

$ yum update
$ yum install ImageMagick-devel

Install ImageMagick on Mac

You need one of Homebrew or MacPorts to install ImageMagick.

Homebrew
$ brew install imagemagick

If seam carving (Image.liquid_rescale()) is needed you have install liblqr as well:

$ brew install imagemagick --with-liblqr
MacPorts
$ sudo port install imagemagick

If your Python in not installed using MacPorts, you have to export MAGICK_HOME path as well. Because Python that is not installed using MacPorts doesn’t look up /opt/local, the default path prefix of MacPorts packages.

$ export MAGICK_HOME=/opt/local

Install ImageMagick on Windows

You could build ImageMagick by yourself, but it requires a build tool chain like Visual Studio to compile it. The easiest way is simply downloading a prebuilt binary of ImageMagick for your architecture (win32 or win64).

You can download it from the following link:

http://legacy.imagemagick.org/script/binary-releases.php#windows

Choose a binary for your architecture:

Windows 32-bit
ImageMagick-6.9.x-x-Q16-x86-dll.exe
Windows 64-bit
ImageMagick-6.9.x-x-Q16-x64-dll.exe

Note

Double check your Python runtime, and ensure the architectures match. A 32-bit Python runtime can not load a 64-bit dynamic library.

Note that you have to check Install development headers and libraries for C and C++ to make Wand able to link to it.

../_images/windows-envvar.png

Lastly you have to set MAGICK_HOME environment variable to the path of ImageMagick (e.g. C:\Program Files\ImageMagick-6.9.3-Q16). You can set it in Computer ‣ Properties ‣ Advanced system settings ‣ Advanced ‣ Environment Variables….

Explicitly define ImageMagick library suffix

New in version 0.5.8.

Wand will attempt to load all popular combinations of ImageMagick’s shared library suffixes. By default, the library suffix would follow a pattern similar to:

             ~~~~~~~~~~      Library Suffix
libMagickWand-7.Q16HDRI.so
             ~~              Major version number. Can be blank, 6, or 7.
                ~~~          Magick Quantum. Can be blank, Q8, or Q16.
                   ~~~~      Optional HDRI-Support. Can be blank, or HDRI

If you have compiled ImageMagick with custom suffixes, you can tell the Wand module how to search for it by setting MAGICK_HOME, like above, and WAND_MAGICK_LIBRARY_SUFFIX environment variables.

The WAND_MAGICK_LIBRARY_SUFFIX would be a semicolon delimited list

$ export WAND_MAGICK_LIBRARY_SUFFIX="-7.Q32;-7.Q32HDRI;.Q32HDRI;.Q32"
$ python3 wand_app.py
