Detailed Description

Reslices a volume along the axes specified.

Date:
2000/12/10 20:08:24
Revision:
1.40
Thanks:
Thanks to David G. Gobbi who developed this class.
vtkImageReslice will re-grid a volume along the axes specified by a matrix. The extent, origin, and sample spacing of the output data can also be set.

The primary uses of this class are to extract either oblique or orthogonal slices from a volume, or to apply either a linear, perspective, or warp transformation to a volume.

This class is the swiss-army-knife of image geometry filters: It can permute, flip, rotate, scale, resample, and pad image data in any combination at similar efficiency to the specialized image filters that do the same things.

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]
 

Use this method, in conjunction with SetOutputOrigin(), SetOutputSpacing() and SetOutputExtent(), to set up a grid of points at which to resample the input.

The Axes specify the axes of the resampling grid, the OutputSpacing specifies the grid spacing, the OutputOrigin specifies the location of the origin of the grid (i.e the coordinates of voxel index (0,0,0) in the coordinate system specified by the Axes), and the OutputExtent specifies the size of resampling grid i.e. the ranges of the (i,j,k) indices.

The first column of the matrix specifies the x-axis vector (set the fourth element to zero), the second column specifies the y-axis, and the third column the z-axis. The fourth column specifies the origin of the axes (set the fourth element to one). The matrix can be used to specify a perspective transformation (i.e. non-zero fourth elements for the axes), but the matrix must be invertible.

virtual vtkMatrix4x4* vtkImageReslice::GetResliceAxes (    )  [virtual]
 

virtual void vtkImageReslice::SetResliceTransform (  vtkAbstractTransform *    )  [virtual]
 

Set a transform to be applied to the resampling grid that was specified in SetResliceAxes().

Note that applying a transform to the resampling grid is equivalent to applying the inverse of the same transform to the image before resampling it. Nonlinear transforms can be used here.

virtual void vtkImageReslice::WrapOff (    )  [virtual]

float   ,
float   
)  [virtual]

NOTE: The OutputOrigin and OutputExtent values are only used if OutputAlwaysCenteredOnInputOff. Otherwise, they are automatically computed.
