[Insight-users] How to call a destructor?

[robert tamburo]

I see.

How about doing something like this?

typedef itk::LineConstIterator<ImageType> IteratorType;
ImageType::IndexType imageIndex;
ImageType::IndexType farPoint;
while()
{
imageIndex = something;
farPoint = somethingelse;
IteratorType it(image, imageIndex, farPoint);
while(!it.IsAtEnd())
{
// do stuff
}
}
