Extract Subset (ExtractGrid)
Extract a subgrid from a structured grid with the option of setting subsample strides.
The Extract Grid filter returns a subgrid of a structured input data set (uniform rectilinear, curvilinear, or nonuniform rectilinear). The output data set type of this filter is the same as the input type.

PropertyDescriptionDefault Value(s)Restrictions
Include Boundary
(IncludeBoundary)
If the value of this property is 1, then if the sample rate in any dimension is greater than 1, the boundary indices of the input dataset will be passed to the output even if the boundary extent is not an even multiple of the sample rate in a given dimension. 0

Only the values 0 and 1 are accepted.

 
Input
(Input)
This property specifies the input to the Extract Grid filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkImageData, vtkRectilinearGrid, vtkStructuredPoints, vtkStructuredGrid.

 
Sample Rate I
(SampleRateI)
This property indicates the sampling rate in the I dimension. A value grater than 1 results in subsampling; every nth index will be included in the output. 1

The value must be greater than or equal to 1.

 
Sample Rate J
(SampleRateJ)
This property indicates the sampling rate in the J dimension. A value grater than 1 results in subsampling; every nth index will be included in the output. 1

The value must be greater than or equal to 1.

 
Sample Rate K
(SampleRateK)
This property indicates the sampling rate in the K dimension. A value grater than 1 results in subsampling; every nth index will be included in the output. 1

The value must be greater than or equal to 1.

 
V OI
(VOI)
This property specifies the minimum and maximum point indices along each of the I, J, and K axes; these values indicate the volume of interest (VOI). The output will have the (I,J,K) extent specified here. 0 0 0 0 0 0

The values must lie within the extent of the input dataset.
