Universal Desktop Ruler

Rulers are great for straight line distances, but would a ruler be a good
choice to measure the length of a river or road? What if you are measuring a
distance along roads from one city to another? How would you measure curved
lines with a straight ruler?
Univerasl Desktop Ruler allows you to measure not only a straight line
distance but any curved distance on the Screen. It allows you to measure
quickly and accurately distances, areas and perimeters of figures on the
screen. You can determine your own scale and get results in pixels and your
units of measurement (feet, inches, meters, ...). It is useful for measuring
distance and area on a map, finding area and perimeter in a house project
for example. Additionally it has a screen magnifier function.
