Detailed Description

template<typename TFraction>
struct DGtal::StandardDSLQ0< TFraction >::ConstIterator

The iterator to move in the standard digital straight line, point by point. To move from A to B on the DSL D, visiting [A,B], write:

       for ( ConstIterator it = D.begin( A ), it_end = D.end( B );
             it != it_end; ++it )
         Point P = *it;
