Member Function Documentation

vtkImageShrink3D* vtkImageShrink3D::New   [static]

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkImageToImageFilter.

virtual const char* vtkImageShrink3D::GetClassName   [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

int vtkImageShrink3D::IsTypeOf const char *    type [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

virtual int vtkImageShrink3D::IsA const char *    type [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

vtkImageShrink3D* vtkImageShrink3D::SafeDownCast vtkObject   o [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

void vtkImageShrink3D::PrintSelf ostream &    os,
vtkIndent    indent

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageToImageFilter.

virtual void vtkImageShrink3D::SetShrinkFactors int   ,
int   ,

Set/Get the shrink factors

virtual void vtkImageShrink3D::SetShrinkFactors int   [3] [virtual]

virtual void vtkImageShrink3D::GetShrinkFactors int &   ,
int &   ,
int &   

virtual void vtkImageShrink3D::GetShrinkFactors int   [3] [virtual]

virtual void vtkImageShrink3D::SetShift int   ,
int   ,

Set/Get the pixel to use as origin.

virtual void vtkImageShrink3D::SetShift int   [3] [virtual]

virtual int* vtkImageShrink3D::GetShift   [virtual]

virtual void vtkImageShrink3D::GetShift int &   ,
int &   ,
int &   

virtual void vtkImageShrink3D::GetShift int   [3] [virtual]

void vtkImageShrink3D::SetAveraging int   

Choose Mean, Minimum, Maximum, Median or sub sampling. The neighborhood operations are not centered on the sampled pixel. This may cause a half pixel shift in your output image. You can changed "Shift" to get around this. vtkImageGaussianSmooth or vtkImageMean with strides.

void vtkImageShrink3D::ExecuteInformation vtkImageData   inData,
vtkImageData   outData
[protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageShrink3D::ComputeInputUpdateExtent int    inExt[6],
int    outExt[6]
[protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageShrink3D::ExecuteInformation   [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter.

Definition at line 116 of file vtkImageShrink3D.h.

void vtkImageShrink3D::ThreadedExecute vtkImageData   inData,
vtkImageData   outData,
int    ext[6],
int    id
[protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkImageToImageFilter.
