#include <dir_struct_elt_incr_update.hh>
This canvas browse all the point of an image 'input' of type 'I', of dimension 'dim' in the direction 'dir' with considering weigh the 'length' nearest points.
The functor should provide (In addition to 'input', 'I', 'dim', 'dir' and 'length') six methods :
F shall features :
{
--- as types:
I;
--- as attributes:
dim;
dir; // and test dir < dim
input;
p;
length;
--- as methods:
void init();
void init_line();
void add_point(q)
void remove_point(q)
void next();
void final();
}
