Actually it does seem to work just not the way expected perhaps.
Looking at the fuzz option on ImageMagick's site
(http://www.imagemagick.org/script/command-line-options.php#fuzz), "The distance can be in
absolute intensity units or, by appending % as a percentage of the maximum possible intensity (255,
65535, or 4294967295)."
As it requires a float, the percentage value won't work so it actually one of the max intensity
values. In my case, the images I was working with seemed to have max intensity values of 65535. So
a fuzz of 6500, for roughly 10%, seemed to do the trick.
The part that might be problematic though is how do you determine the max intensity of a
color/image? Using a static 6500 would be fine until I would have to convert an image with a max
intensity other than 65535. If it's 255 it would wipe the entire image. Or fall far short on
the fuzz with the larger value.
