[Image-SIG] Scan Image for blank spots using PIL

[Greg Corradini]

Hello,
I want to use PIL to scan a newly created image for possible corrupt (blank)
pixels.

The PIL documentation doesn't seem to mention what value a blank pixel might
have (I assume it would come back as None).  I'm not sure what to test for.

I see the Image module has a verify
function<http://www.pythonware.com/library/pil/handbook/image.htm>,
but I'm not sure if that covers validating that pixels are not blank.

Any ideas?

Thanks
