Detailed Description

subsample an image dataset

vtkImageSubSample is a filter that samples in image dataset based on the specified sample rate. The filter differs from vtkExtractVOI in that specific regions cannot be extracted (operates on the entire dataset) and the user may specify a non-integer sample rate. Sampling is performed evenly in each dimension. Sampling rates less than 1 are set to 1 (use vtkImageConstantPad to increase the size of the image).

Construct object to extract all of the input data.

Reimplemented from vtkAlgorithm.

virtual void vtkImageSubSample::SetSampleRate	(	float	,
		float	,
		float
	)			[virtual]

Set the sampling rate in the i, j, and k directions. If the rate is > 1, then the resulting image will be the 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.
