[magick-users] smarter sprite collection

[bw]

Hi,

I had the following idea.

I want to make one file of around 250 small png flags (all flags are square
btw) for sprite purposes.

Now as discussed earlier somewhere, placing vertically the same colour will
reduce the png better than horizontally so I need to find a good way to
group them

First I guess removing duplicate flags will help ;-) but then the hard part:
grouping as much as possible: but how?

Could there be an automated way to check vertically resemblance between the
flags? and group them somehow?

cheers,
