Re: how to count % color coverage?

My best wish would be:

Color 0: 1.4%
Color 2: 4.5%
Color 10: 50.1%

(% of surface, image extension)

maybe something biologic software?
(my photo are photo of a paper with spot to measure)

thank you.


maybe not the most useful or easiest solution but maybe if you know a
little bit of programming and php at hand then the function
"imagecolorat" (http://at2.php.net/manual/en/function.imagecolorat.php)
can do what you want...
