pgmagick is a yet another boost.python based wrapper for GraphicsMagick.
install to:
$ pip install pgmagick
Python2.5++, GraphicsMagick and Boost.Python.
package install on Ubuntu(test on Ubuntu10.04+):
### Ubuntu11.10+ ### $ apt-get install python-pgmagick ### Ubuntu10.04+ ### $ apt-get install libgraphicsmagick++1-dev $ apt-get install libboost-python1.40-dev
package install on Fedora:
$ yum install GraphicsMagick-c++-devel $ yum install boost-devel
GraphicsMagick from source package:
$ ./configure --enable-shared=yes $ make && make install
$ brew tap hhatto/pgmagick $ brew install pgmagick
update 2014.05.12 on MacOSX 10.9.2 (add ARCHFLAGS):
$ brew install graphicsmagick $ brew install boost --with-python $ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install pgmagick
update 2013.08.31 with Homebrew
$ brew install graphicsmagick # or imagemagick $ brew install boost --with-thread-unsafe --build-from-source $ pip install pgmagick
install reported on MacOSX, Thanks Rohan Singh and Simon Harrison.

Now, not official support. However, unofficial binary packages exists.
pgmagick is supported to ImageMagick library. (version:0.4+)
package install on Ubuntu(test on Ubuntu10.04+):
$ apt-get install libmagick++-dev
show library name and version:
>>> from pgmagick import gminfo >>> gminfo.library 'GraphicsMagick' # or 'ImageMagick' >>> gminfo.version '1.3.x' >>>
scale example:
>>> from pgmagick import Image, FilterTypes >>> im = Image('input.jpg') >>> im.quality(100) >>> im.filterType(FilterTypes.SincFilter) >>> im.scale('100x100') >>> im.sharpen(1.0) >>> im.write('output.jpg')
composite example:
>>> from pgmagick import Image, CompositeOperator as co >>> base = Image('base.png') >>> layer = Image('layer_one.png') >>> base.composite(layer, 100, 100, co.OverCompositeOp) >>> im.write('output.png')
draw example:
>>> from pgmagick import Image, DrawableCircle, DrawableText, Geometry, Color >>> im = Image(Geometry(300, 300), Color("yellow")) >>> circle = DrawableCircle(100, 100, 20, 20) >>> im.draw(circle) >>> im.fontPointsize(65) >>> text = DrawableText(30, 250, "Hello pgmagick") >>> im.draw(text) >>> im.write('hoge.png')
blob access:
>>> from pgmagick import Image, Blob, Geometry >>> blob = Blob(open('filename.jpg').read()) >>> blob.update(open('filename2.jpg').read()) >>> img = Image(blob, Geometry(600, 480)) >>> img.scale('300x200') >>> img.write('out.jpg')
create animated-GIF:
from pgmagick import Image, ImageList, Geometry, Color imgs = ImageList() for color in ('red', 'blue', 'green', 'black', 'yellow'): imgs.append(Image(Geometry(200, 200), Color(color))) imgs.animationDelayImages(100) imgs.scaleImages(Geometry(100, 100)) imgs.writeImages('output.gif')
more API detail... read to Magick++ API for GraphicsMagick document.
Python APIs(NOTICE!! this api is alpha version!!):
>>> from pgmagick.api import Image >>> img = Image((300, 300), "gradient:#ffffff-#000000") >>> img.scale(0.8) >>> img.write('out.png')
