Project description
About
pgmagick is a yet another boost.python based wrapper for GraphicsMagick.
Installation
install to:
$ pip install pgmagick
Requirements
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
MacOSX
via homebrew-cask(homebrew-pgmagick)
$ brew tap hhatto/pgmagick $ brew install pgmagick
via homebrew and pip
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.
Windows
Now, not official support. However, unofficial binary packages exists.
ImageMagick support
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' >>>
Usage
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')
