Detailed Description

Reslices a volume along a new set of axes.

Date:: 2002/12/11 14:26:22

Revision:: 1.10

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.

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.
