Wand¶
Wand is a ctypes
-based simple ImageMagick binding for Python.
from wand.image import Image
from wand.display import display
with Image(filename='mona-lisa.png') as img:
print(img.size)
for r in 1, 2, 3:
with img.clone() as i:
i.resize(int(i.width * r * 0.25), int(i.height * r * 0.25))
i.rotate(90 * r)
i.save(filename='mona-lisa-{0}.png'.format(r))
display(i)
You can install it from PyPI (and it requires MagickWand library):
$ apt-get install libmagickwand-dev
$ pip install Wand
Why just another binding?¶
There are already many MagickWand API bindings for Python, however they are lacking something we need:
Pythonic and modern interfaces
Good documentation
Binding through
ctypes
(not C API) — we are ready to go PyPy!Installation using pip
Requirements¶
Python 3.3 or higher
CPython 3.3 or higher
PyPy 1.5 or higher
MagickWand library
libmagickwand-dev
for APT on Debian/Ubuntuimagemagick
for MacPorts/Homebrew on MacImageMagick-devel
for Yum on CentOS
