void SetExtent(int *extent);
DESCRIPTION
vtkStructuredGridGeometryFilter is a filter that extracts geometry from a structured grid. By specifying appropriate i-j-k indices, it is possible to extract a point, a curve, a surface, or a "volume". Depending upon the type of data, the curve and surface may be curved or planar. The volume is actually a (n x m x o) region of points.
The extent specification is zero-offset. That is, the first k-plane in a 50x50x50 structured grid is given by (0,49, 0,49, 0,0).
CAVEATS
If you don't know the dimensions of the input dataset, you can use a large number to specify extent (the number will be clamped appropriately). For example, if the dataset dimensions are 50x50x50, and you want a the fifth k-plane, you can use the extents (0,100, 0,100, 4,4). The 100 will automatically be clamped to 49.

SUMMARY
int *GetExtent()
void GetExtent(int data[6])
Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).
vtkStructuredGridGeometryFilter()
Construct with initial extent (0,100, 0,100, 0,0) (i.e., a k-plane).
void SetExtent(int iMin, int iMax, int jMin, int jMax, int kMin, int kMax)
Specify (imin,imax, jmin,jmax, kmin,kmax) indices.
void SetExtent(int *extent)
Specify (imin,imax, jmin,jmax, kmin,kmax) indices in array form.
