vtkImageReslice is the swiss-army-knife of image geometry filters: It can permute, rotate, flip, scale, resample, deform, and pad image data in any combination with reasonably high efficiency. Simple operations such as permutation, resampling and padding are done with similar efficiently to the specialized vtkImagePermute, vtkImageResample, and vtkImagePad filters. There are a number of tasks that vtkImageReslice is well suited for:

1) Application of simple rotations, scales, and translations to an image. It is often a good idea to use vtkImageChangeInformation to center the image first, so that scales and rotations occur around the center rather than around the lower-left corner of the image.

2) Resampling of one data set to match the voxel sampling of a second data set via the SetInformationInput() method, e.g. for the purpose of comparing two images or combining two images. A transformation, either linear or nonlinear, can be applied at the same time via the SetResliceTransform method if the two images are not in the same coordinate space.

3) Extraction of slices from an image volume. The most convenient way to do this is to use SetResliceAxesDirectionCosines() to specify the orientation of the slice. The direction cosines give the x, y, and z axes for the output volume. The method SetOutputDimensionality(2) is used to specify that want to output a slice rather than a volume. The SetResliceAxesOrigin() command is used to provide an (x,y,z) point that the slice will pass through. You can use both the ResliceAxes and the ResliceTransform at the same time, in order to extract slices from a volume that you have applied a transformation to.

Warning:
This filter is very inefficient if the output X dimension is 1.

Member Function Documentation

vtkImageReslice* vtkImageReslice::New (    )  [static]
 

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

Reimplemented from vtkImageToImageFilter.

virtual const char* vtkImageReslice::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 vtkImageReslice::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 vtkImageReslice::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.

vtkImageReslice* vtkImageReslice::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.

virtual void vtkImageReslice::PrintSelf (  ostream &    os,
vtkIndent    indent
)  [virtual]
 

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 vtkImageReslice::SetResliceAxes (  vtkMatrix4x4 *    )  [virtual]
 

This method is used to set up the axes for the output voxels. The output Spacing, Origin, and Extent specify the locations of the voxels within the coordinate system defined by the axes. The ResliceAxes are used most often to permute the data, e.g. to extract ZY or XZ slices of a volume as 2D XY images.

The first column of the matrix specifies the x-axis vector (the fourth element must be set to zero), the second column specifies the y-axis, and the third column the z-axis. The fourth column is the origin of the axes (the fourth element must be set to one).

An alternative to SetResliceAxes() is to use SetResliceAxesDirectionCosines() to set the directions of the axes and SetResliceAxesOrigin() to set the origin of the axes.

void vtkImageReslice::ComputeInputUpdateExtents (  vtkDataObject *    output )  [protected, virtual]
 

What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses.

Reimplemented from vtkImageToImageFilter.

void vtkImageReslice::ComputeInputUpdateExtent (  int    inExt[6],
int    outExt[6]
)  [protected, virtual]
 

Reimplemented from vtkImageToImageFilter.

void vtkImageReslice::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.
