[Insight-users] check boundary Iterator...

[Mr Gaffe]

hello,

I would like to know how can I check when I am out of
my image when I use a: "NeighborhoodIterator".
Since boundary condition are set to on by default, I
would like to know when it is happen because I don't
want to add this index ...

this is the global idea of my program:

      it.SetLocation (piIndex); // valid index, 
      for (unsigned i = 0; i < it.Size (); i++)
	{

	  w = it.GetPixel (i);
	  qiIndex = piIndex + it.GetOffset (i);

=> Problem: qiIndex can be outside my Image, so I
would like something like:
if (it.boundaryCondition==OK)
       qiIndex = piIndex + it.GetOffset (i);
else
   // do nothing


thanks for help,

lagaffe
