[Insight-users] Segmentation Fault when using Iterators

[Oliver Trebbe]

Hi guys,

ive got a problem: my Iterators dont want to Iterate right:

Code snippet:

void probchecker::probcheck( )
{
  NCSIteratorType probIt( m_ProbImage, m_ProbImage->GetRequestedRegion() );
  NCSIteratorType lobeIt( m_LobeImage, m_LobeImage->GetRequestedRegion() );

 
  probIt.SetFirstDirection(  1 );
  probIt.SetSecondDirection( 2 );
  lobeIt.SetFirstDirection(  1 );
  lobeIt.SetSecondDirection( 2 );

  probIt.GoToBegin();
  lobeIt.GoToBegin();
 
  ImageType3D::IndexType probItIndex;
 
  while( !probIt.IsAtEnd() || !lobeIt.IsAtEnd() )
  {
    while( !probIt.IsAtEndOfSlice() || !lobeIt.IsAtEndOfSlice() )
    {
      while( !probIt.IsAtEndOfLine() || !lobeIt.IsAtEndOfLine() )
      {
... and so on...
if i just test the lobeIt.IsAtEnd() in the first while loop it breaks 
and everything is over...
so it has something to do with the lobeIt but i cant find ane failure...
bug maybe?

would be pleased about any help


Regards

Oliver
