get the coordinates of an image seperated in two parts

[Noks]

Hello Everyone,
I am a noob as far as ImageMagic is concerned.I am Using ImageMagick-6.6.4-8-Q16-windows-dll.exe.
I have an image in which there is a green continuous part and a red continuous part.I need to get the coordinates of the line seperating those colors; can some one give me the exact command.And could you people suggest a tutorial to get started with Image MAgic on Windows.
Thanks

better to post a link to your image so others can see what you are describing and see if there is some solution.

I don't see anything meaningful at that link. It says 1x1 pixels.

see txt: format at http://www.imagemagick.org/Usage/files/#txt

The following converts your image to txt: format, then uses unix to find all pixels that are black, then selects the x,y coordinates and sorts according the the x coordinate.

convert OLV2J-46acc24e.png txt:- | grep "black" | sed -n 's/^\(.*\):.*$/\1/p' | sort -t , -k 1 -n

As i told in the first post i am using ImageMagick-6.6.4-8-Q16-windows-dll.exe.On runnning this command in Windows CMD i get an error as:
grep not found...But convert works fine...Which version supports such commands on windows....anyways thanks for the rep...i will use linux and get the work done...
Thanks

Sorry, I am on a Mac and only know unix. Perhaps one of the Windows users can give you the equivalent commands.

Or you can install Cygwin and the IM version for Cygwin. See http://www.imagemagick.org/script/binary-releases.php
