Open Source Java Test and Measurement Software

On-Screen Protractor is a simple java application that allows to measure an angle on the screen. Originally the program was conceived to assess the angle between north and a given point on any map open on the screen, therefore the background of the application window is transparent and the angle is measured from the positive y-axis and clockwise. The application allows to move the origin of reference axes and to rotate the axes as needed. OnScreenProtractor works correctly only in Windows context. In linux 'OnScreenProtractor_v0.6.exe' can be started with 'Wine'

This app has an educational purpose only. It demonstrates a very simple application to convert temperatures between Celsius, Kelvin and Fahrenheit scales
