The `graphics` object is not initialized anywhere inside the class, where it is expected to set explicitly by the user. When the user doesn't set it and try to use the any mehtods like `drawing/setFont`, NPE is raised which is expected. The scenario is taken care by checking if the `graphics` object is null before using it inside the class, thus eliminating the NPE case.

I think auto indentation has caused this, will undo these tabs changes.
