Doing graphics design, and want to do a quick measurement of a screen element? Then head over to your Software Manager and search for KRuler.
Kruler is a simple, and easy to configure ruler that you can use to measure the pixel width or length of an on-screen element.
I’ve had it installed all of 3 days, and I’ve already used it a dozen times while designing our yearly Christmas card.
You can easily change the size and orientation of KRuler, as well as the color. Yes Gimp and other graphics editors have a ruler function, but with KRuler you don’t need to open them to take a quick measurement.
Give it a try, you may find it handy too!
