Trilithon Protractors is another innovative application specifically for Mac OS X. This feature-rich product meets the needs of web developers and graphic designers by providing precision measurement of angles.
- Protractor Scales include Degrees (the standard 360 gradations in a circle); Radians (2? gradations in a circle); Grads (a common European standard with 400 gradations in a circle); Mils (a military system with 6400 gradations in a circle) Compass Rose (a compass with 32 principal points)
- Direction of Measurements can be set to Widdershins (anti-clockwise--the standard direction) or Deasil (clockwise--the retrograde direction)
- Zero Points can be set to multiples of 90, 30, and 45 degrees for the Degree protractor; to multiples of 100 and 50 grads for the Grad protractor; and to multiples of 1600 and 800 mils for the Mil protractor;
- Opacity Menu can set Protractors fully opaque, or can set them semi-transparent in ten percent increments so that you can see through to the underlying content
- Real-Time Interactive Tracking of the mouse, plus high-precision display of current angle, with major and minor tracking lines
- Move Protractors around the screen, either by dragging with the mouse, or via the arrow keys
- Background Colour can be set to one of eight different colours
- Set Centre Point of Protractor using command-O to position the centre point of the protractor to the current location of the mouse
- Copy Current Angle to the pasteboard using command-C for pasting into other applications
- Lock Tracking Lines using command-L to take screen shot of angles
- Remember Settings across sessions
