io/boards/dgtalBoard2D-3-custom-points.cpp

This example shows you how to modify the style of each drawable elements. It is a matter of creating a custom style class which gives in its method setStyle the specific style parameters. Then, you attach this style to your drawable elements with an instance of CustomStyle outputed in the Board2D stream.
