Re: [Image-SIG] Comparison of PIL and GD speed for setting pixels through python

With prompting from Chris, and a little further work in gd, I have updated this comparison further, adding a further gd/ctypes test, this time setting pixel values using the raw pixel data, as well as the start of a test for a numpy/PIL option. Unfortunately it doesn't fully work, at least wit

[Image-SIG] cannot import from PIL when easy_installed

When you install PIL via easy_install, you cannot import from the PIL module. Is this a bug in PIL or in code that tries to import "from PIL"? >>> import PIL Traceback (most recent call last): File "", line 1, in ? ImportError: No module named PIL >>> import Image #no error This is h
