A tool to measure distances and angles on the desktop.
The distances can be measured in pixel, cm, inch, points or twips and the angle in radiant or degree.
The ruler is almost transparent so you can have it on the screen, while you are working with the applications below.
Additionally it has a screen loupe and a RGB value window.
You can also draw points, lines, rectangles, polylines, bitmaps and text as temporary objects on the screen.

Screen Loupe is a small utility that displays a magnified view of whatever is beneath the mouse cursor, much like a jeweler's or printer's loupe. You can copy the contents of the Loupe window to the clipboard as well. The captured image can be pasted into any graphics program and most word processors. Screen Loupe's main viewing window can be resized, and an option is included to lock the current view.
