Download - PixelRuler

Current version: PixelRuler

[Version history]

PixelRuler can be used with limited functionality only for private use free of charge.

The free version can only display an horizontal ruler, and it is not possible to run the program multiple times - in addition, an information window is displayed each time the program is started, which contains a link to purchase the full version. Multiple rulers, distance, angle measurement and golden ratio are only supported during a 1-week trial period.

The price for commercial use is only 4.95€* for one license (1 workstation). You get a volume discount when you purchase multiple licenses. More Info...

After receipt of payment (and a personal check of the payment and order data on my part), the buyer will receive a link per e-mail to receive the license key, which converts the free version into a full version.

  • New menu item "show Coordinates on Ruler / Angle from 0|0 (purple)" to output the Angle function I from the coordinate origin 0|0 of the ruler to the mouse pointer (using atan2, in the right-hand Cartesian coordinate system).
  • Angle function II integrated in the measuring function of the ruler, to output the angle by setting the 1st measuring point as the coordinate origin 0|0, and a 2nd measuring point (using atan2, in the right-hand Cartesian coordinate system).
