|
|
*
|
|
* The vtkCheckerboardRepresentation is used to implement the representation of
|
|
* the vtkCheckerboardWidget. The user can adjust the number of divisions in
|
|
* each of the i-j directions in a 2D image. A frame appears around the
|
|
* vtkImageActor with sliders along each side of the frame. The user can
|
|
* interactively adjust the sliders to the desired number of checkerboard
|
|
* subdivisions. The representation uses four instances of
|
|
* vtkSliderRepresentation3D to implement itself.
