[vtkusers] cross hairs display issue with vtkImageViewer2 and vtkResliceCursorWidget

[Liu_tj]

Hi, VTK guys,


I uses vtkImageViewer2 to display DICOM series. the vtkResliceCursorWidget is enabled. Mousewheel forward and backward is for slice switching. However, when slice is switched, the two cross hairs is overlaied by the new slice. What should I do to avoid it? 
Refer to the attachement for the cross hair display issue.


Thanks,
Liu Peng
