Koen,
Thanks for the bug report (and the fix!). I'm testing it now and the fix should be available in an
hour.

Bill

Subject: [Insight-users] Bug in itkImageRegion


Hi all, 

I think there is a bug in itkImageRegion::IsInside(const 
ContinuousIndex<TCoordRepType,ImageDimension> &): indices outside a region 
are actually reported to fall inside. Here is some example code reproducing 
the error:

  typedef itk::ImageRegion<1>        RegionType;
  RegionType::IndexType    index = {0};
  RegionType::SizeType     size = {100};
  RegionType region(index, size);
  itk::ContinuousIndex<double, 1>  continuousIndex;
  continuousIndex[0] = 99.9;
  std::cout << region.IsInside( continuousIndex ) << std::endl;

In itkImageRegion::IsInside(const 
ContinuousIndex<TCoordRepType,ImageDimension> &), the test "if( index[i] >= 
bound )" should probably be replaced with "if ( index[i] > bound-1 )"

Cheers,

Koen
