Detailed Description

This class stored a single point. As all coordinates it is store as an integer with a resolution of 32 bit. The physical coordinates can be calculated by a multiplication with the databaseunits (class drawingField)

Example:

   1  point p;
   2  p.set(10000,10000);
   3  int x=p.x();
