Hi!
I wonder if it is possible to do something like the following with the Python
Imaging library:
for pixel in image:
get how close to black it is
register what would be the darkest shade found in the image
delete pixels lighter than the darkest.
I'm asking because I scanned a bunch of pages from a book to .jpg. The images
are in grayscale, and some pages have tables with gray background "underneath"
black text, and I wanted to get rid of the background.
Thanks,
Eduardo
