io/boards/dgtalBoard2D-2-sets.cpp

This simple example shows also some basic usage of a Board2D to export graphical representations of dgtal objects (here, a digital set and a digital object). Note also the use of different modes that may be defined for some classes. An object may thus be displayed just as a set of points, but also as a set of points with neighborhood structure (a graph).

visualization of resulting export (first export dgtalBoard2D-2-sets-1).
