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) with Python2
$ brew tap hhatto/pgmagick $ brew install pgmagick
via homebrew-cask(homebrew-pgmagick) with Python3
with –with-python3 option:
$ brew install pgmagick --with-python3
via homebrew and pip with Python3
on MacOSX 10.11.6:
$ brew install graphicsmagick $ brew install boost-python --with-python3 $ pip install pgmagick
via homebrew and pip with Python2
update 2017.05.17 on MacOSX 10.11.6:
$ brew install graphicsmagick $ brew install boost-python $ pip 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
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
>>> im = Image('input.jpg')
>>> im.quality(100)
>>> im.scale('100x100')
>>> im.sharpen(1.0)
>>> im.write('output.jpg')
resize example:
>>> from pgmagick import Image
>>> im = Image('input.jpg')
>>> im.filterType(FilterTypes.SincFilter)
>>> im.resize('100x100')
>>> 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')
