I've tried lots of solution that posted on the net, they don't work.
>>> import _imaging
from PIL import Image, ImageDraw, ImageFilter, ImageFont
im = Image.new('RGB', (300,300), 'white')
draw = ImageDraw.Draw(im)
font = ImageFont.truetype('arial.ttf', 14)
draw.text((100,100), 'test text', font = font)
ImportError: The _imagingft C module is not installed
File "D:\Python26\Lib\site-packages\PIL\ImageFont.py", line 34, in __getattr__
raise ImportError("The _imagingft C module is not installed")
Your installed PIL was compiled without libfreetype.
You can get precompiled installer of PIL (compiled with libfreetype) here (and many other precompiled Python C Modules):
