Detailed Description

Reslices a volume along a new set of axes.

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 transformations (either linear or nonlinear) to an image. It is sometimes convenient 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 SetOutputDirection() to specify the orientation of the output slices. The columns of the direction matrix specify the x, y, and z axes for the output volume or slice, and SetOutputOrigin() can be used to specify the position. You can use these methods together with SetResliceTransform() in order to extract slices in a certain orientation while simultaneously applying a transformation to the coordinate system.

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

◆ SetResliceAxes()

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.

◆ SetResliceTransform()

virtual void vtkImageReslice::SetResliceTransform ( vtkAbstractTransform * )

virtual

Set a transform to be applied to the resampling grid that has been defined via the ResliceAxes and the output Origin, Spacing and Extent.

Note that applying a transform to the resampling grid (which lies in the output coordinate system) is equivalent to applying the inverse of that transform to the input volume. Nonlinear transforms such as vtkGridTransform and vtkThinPlateSplineTransform can be used here.

virtual

Set a transform to be applied to the resampling grid that has been defined via the ResliceAxes and the output Origin, Spacing and Extent.

Turn this on if you want to guarantee that the extent of the output will be large enough to ensure that none of the data will be cropped (default: Off).

◆ SetBorder()

virtual void vtkImageReslice::SetBorder ( vtkTypeBool )

virtual

Extend the apparent input border by a half voxel (default: On).

This changes how interpolation is handled at the borders of the input image: if the center of an output voxel is beyond the edge of the input image, but is within a half voxel width of the edge (using the input voxel width), then the value of the output voxel is calculated as if the input's edge voxels were duplicated past the edges of the input. This has no effect if Mirror or Wrap are on.

virtual

Extend the apparent input border by a half voxel (default: On).

This changes how interpolation is handled at the borders of the input image: if the center of an output voxel is beyond the edge of the input image, but is within a half voxel width of the edge (using the input voxel width), then the value of the output voxel is calculated as if the input's edge voxels were duplicated past the edges of the input.
