<p>How can I read the colors of an image with python using google app engine?</p>

<p><strong>Example:</strong> I like to build a function to determine the most striking colors of an image to set a harmonic background color for it.</p>

The
Images API
does not (currently) contain pixel-level functions. To quote the overview document:
Note: In order to use the Images API in your local environment you must first download and install PIL, the Python Imaging Library. PIL is not available on App Engine; it is only used as a stub for the Images API in your local environment. Only the transforms provided in the images API are available on App Engine.
The community has been asking for full
PIL
support for some time, but it looks like we'll have to wait.
