// .NAME vtkExtractRectilinearGrid - Extract a sub grid (VOI) from the structured rectilinear dataset.
// .SECTION Description
// vtkExtractRectilinearGrid rounds out the set of filters that extract
// a subgrid out of a larger structured data set. RIght now, this filter
// only supports extracting a VOI. In the future, it might support
// strides like the vtkExtract grid filter.
// .SECTION See Also

// Description:
// Specify i-j-k (min,max) pairs to extract. The resulting structured grid
// dataset can be of any topological dimension (i.e., point, line, plane,
// or 3D grid).

// Description:
// Set the sampling rate in the i, j, and k directions. If the rate is > 1,
// then the resulting VOI will be subsampled representation of the input.
// For example, if the SampleRate=(2,2,2), every other point will be
// selected, resulting in a volume 1/8th the original size.

// Description:
// Control whether to enforce that the "boundary" of the grid is output in
// the subsampling process. (This ivar only has effect when the SampleRate
// in any direction is not equal to 1.) When this ivar IncludeBoundary is
// on, the subsampling will always include the boundary of the grid even
// though the sample rate is not an even multiple of the grid
// dimensions. (By default IncludeBoundary is off.)
