Documentation for vtkImageReslice

vtkImageReslice - Reslices a volume along the axes specified.

Description:

vtkImageReslice will reslice a volume along the axes specified by the reslicing transformation matrix. The extent, origin, and sampling density of the output data can also be set.

Caveats:

Interpolation cannot (yet) be used on a 2D image because the trilinear interpolation requires a cube of eight input voxels for each output voxel.

Detailed Method Descriptions:

Set reslicing transform (describes the set of axis along which to reslice)

	void SetResliceTransform (vtkTransform *)
	vtkTransform *GetResliceTransform ()

Turn on trilinear interpolation (default: nearest neighbor)

	void SetInterpolate (int )
	int GetInterpolate ()
	void InterpolateOn ()
	void InterpolateOff ()

Allow user to set background 'color'

	void SetBackgroundLevel (double )
	double GetBackgroundLevel ()

Spacing, origin, and extent of output data

	void SetOutputSpacing (float ,float ,float )
	void SetOutputSpacing (float *)
	float *GetOutputSpacing ()
	void SetOutputOrigin (float ,float ,float )
	void SetOutputOrigin (float *)
	float *GetOutputOrigin ()
	void SetOutputExtent (int *)
	int *GetOutputExtent ()

This method is passed a input and output region, and executes the filter algorithm to fill the output from the input. It just executes a switch statement to call the correct function for the regions data types.
