About

pgmagick is a yet another boost.python based wrapper for GraphicsMagick.

Install

install to:

$ pip install pgmagick

Require

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

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')
