Calibration is required for correct coordinates of points in the table (corresponding real). To start calibration, you should load the file and click button <Calibration> in the lower part of the program window (or "Actions"->"Calibration"). Calibration must be performed manually. It consists of three successive stages:
It is needed for each image pursue new calibration. Upon completion of calibration coefficients will be created translation of coordinates of points on the image in real terms. Now you can start converting graphics (Look Conversion).
Note: It is not recommended during calibration resize the program window as the image is stretched on the window. This can lead to errors in calibration, and hence to incorrect results. Minimizing the window does not interfere with calibration.
