Detailed Description

Multi-dimensional image iterator which only walks a region.A multi-dimensional image iterator that extends the ImageLinearConstIteratorWithIndex from iteration along lines in an image to iteration along both lines and planes (slices) within an image. A slice is defined as a 2D plane spanned by two vectors pointing along orthogonal coordinate axes. The slice orientation of the iterator is defined by specifying its two spanning axes using the methods:.

 SetFirstDirection(n)
 SetSecondDirection(n)

where n is the number of the axis.

Use the following methods to move the iterator between slices:

 NextSlice()
 PreviousSlice()

To test the position of the iterator with respect to the end or beginning of the slice use the following methods:

 IsAtReverseEndOfSlice()
 IsAtEndOfSlice()

The following code, for example, illustrates the typical use of this iterator. For more information please see the Software Guide.

 ImageSliceConstIteratorWithIndex<ImageType> it( image, image->GetRequestedRegion() );
 
 it.SetFirstDirection(2);
 it.SetSecondDirection(0);

 it.GoToBegin();
 while( !it.IsAtEnd() )
 {
   while( !it.IsAtEndOfSlice() )
   {
     while( !it.IsAtEndOfLine() )
     {
        value = it.Get();  // it.Set() doesn't exist in the Const Iterator
        ++it;
     }
     it.NextLine();
   }
   it.NextSlice();
  }
