README

pyninepatch is a python library and command line tool for rendering android-style 9-patch images. (see: http://developer.android.com/guide/topics/graphics/2d-graphics.html)

pyninepatch requires the Python Imaging Library (http://pypi.python.org/pypi/PIL/).

KNOWN ISSUES

• images with multiple stretchable areas may end up rendering one or two pixels short due to rounding errors.
• it's not super efficient.

EXAMPLES

Render a 9-patch to a specific size and display it on screen

CLI

$ python ninepatch.py myninepatch.9.png --size 800x600

Python

>>> import ninepatch, Image
>>> np = ninepatch.NinePatch("myninepatch.9.png")
>>> np.render((800,600)).show()

Render a 9-patch around a content image and save it to disk.

CLI

$ python ninepatch.py myninepatch.9.png --content mycontent.png --output output.png

Python

>>> import ninepatch, Image
>>> np = ninepatch.NinePatch("myninepatch.9.png")
>>> img = np.render_around(Image.open("mycontent.png"))
>>> img.save("output.png")
