Hi

I am using C++ and ImageMagick-6.3.6 to do some image function. Now I have an image from CCTV with red color background and a few white rectangles. Those rectangles white color some bright and some dark. How can I find out the color value on those rectangles?


Thanks

In IM, crop a single pixel and output it using txt:-

Better method would probably involve some image viewer, like XV, Gimp, or whatever you like to use.

thank you. i will try on it.
