How to meter pixel on screen

Question

I need to meter pixel on web page or on the screen. I used orange pixel meter is any other program similar to mater pixel on screen.

it seems that "orange pixel meter" is one of those screen pixel ruler programs; but which platform do you need one on? — Dan D., Dec 08 '10 at 22:57
What do you want to measure, exactly? Arbitrary points or DOM tree elements? If it's the latter, use Firebug. — mingos, Dec 09 '10 at 17:54

As reported on Chrome store - full of adware, avoid this solution! – Vexter Dec 12 '13 at 13:22
Bear in mind that my answer was posted *over three years ago*. Back then MeasureIt had no adware. As of Dec 8, 2010, my answer was perfectly valid. Instead of a downvote, I'd restrain myself to just leaving a comment an perhaps adding a note to the answer itself. I cannot be held responsible for what the developers of a given piece of software do with it in the future, you know. – mingos Dec 13 '13 at 10:56
You are correct, I did add a note now and will withdraw the down vote when the edit goes through (since I can't do it at the time unless the answer is edited) – Vexter Dec 14 '13 at 19:45

I can't really tell what you mean but if you want to get the RGB value of a pixel at a particular coordinate, you can use this python script:

#!/usr/bin/python -W ignore::DeprecationWarning
import sys
import gtk

def get_pixel_rgb(x, y):
    pixbuf = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, 1, 1)
    pixbuf.get_from_drawable(gtk.gdk.get_default_root_window(),
                             gtk.gdk.colormap_get_system(), 
                             x, y, 0, 0, 1, 1)
    return pixbuf.get_pixels_array()[0][0]

print get_pixel_rgb(int(sys.argv[1]), int(sys.argv[2]))
