* @class vtkImageSlabReslice
|
|
* @brief Thick slab reformat through data.
|
|
*
|
|
* This class derives from vtkImageResliceBase. Much like vtkImageReslice, it
|
|
* reslices the data. It is multi-threaded. It takes a three dimensional image
|
|
* as input and produces a two dimensional thick MPR along some direction.
|
|
* <p> The class reslices the thick slab using a blending function. Supported
|
|
* blending functions are Minimum Intensity blend through the slab, maximum
|
|
* intensity blend and a Mean (average) intensity of values across the slab.
|
|
* <p> The user can adjust the thickness of the slab by using the method
|
|
* SetSlabThickness. The distance between sample points used for blending
|
|
* across the thickness of the slab is controlled by the method
|
|
* SetSlabResolution. These two methods determine the number of slices used
|
|
* across the slab for blending, which is computed as
|
|
* {(2 x (int)(0.5 x SlabThickness/SlabResolution)) + 1}. This value may
|
|
* be queried via GetNumBlendSamplePoints() and is always >= 1.
|
|
* <p> Much like vtkImageReslice, the reslice axes direction cosines may be
|
|
* set via the methods SetResliceAxes or SetResliceAxesDirectionCosines. The
|
|
* output spacing is controlled by SetOutputSpacing and the output origin is
|
|
* controlled by SetOutputOrigin. The default value to be set on pixels that
|
|
* lie outside the volume when reformatting is controlled by
|
|
* SetBackgroundColor or SetBackgroundLevel. The SetResliceAxesOrigin()
|
|
* method can also be used to provide an (x,y,z) point that the slice will
|
|
* pass through.
