Measuring Stuff On Screen – Review 10

Now, imagine you are a graphic designer, image editor, picture enthusiast (or even a hapless website designer). You need to see the precise distance between two pixels.

What is one to do? Take a screenshot, open the image up in a fancy editor, then look for the helpful image resolution somewhere in the status bar.

KRuler

KRuler is a nice graphical tool for determining those pesky distances. When launched, it places a virtual ruler marked out with pixels on your screen.

While the mouse is over the KRuler window, a straight black arrow extends out from the line. This, in addition to the precise pixel distance displayed at the 0-end, make it significantly easier to measure onscreen distances.

KRuler can do a bit more than just that, though. The colour of the pixel located at the tail of the arrow is shown next to the pixel number. There are also quite a few configuration items available by right-clicking on the ruler. Orientation, transparency, colour, and even the font can be changed if you want to.

Overall, I’d say that this is indispensable for those times when you need a ruler.
