A Coordinate Measuring Tool to read Data from Curves .Net framework also provides rich utilities for graphics, such as GDI+. In the Figure below the scanned picture with the curves to be measured is loaded into the panel as background picture. Mouse-clicking is made against the points on a curve to draw another curve, in order to make sure the clicking is not off the line. For every click the coordinate is recorded. The coordinate is immediate calculated into the physical value based on an initial setup against the coordinate system in the picture. So in the first step, the coordinate system is configured. Then the values in a curve are measured. The value from every click is displayed on the form for double checking. Then click “Submit” button to send data to database or “Clear” to clear data. The precisions of the data to send to database are adjustable. The size for the panel to display source curves can also be changed to fit various pictures.
