Hi vtk users,

I would like to create a line that goes through the image.But when I
tried this I can only see the lines on the sides, it doesn't go through
the image. Could you please help me with this issue. 

set Line [vtkLineSource New]
    $Line SetPoint1 -50 100 28
    $Line SetPoint2 250 100 28
set LineMapper [vtkPolyDataMapper New] 
    $LineMapper SetInput [$Line GetOutput]

set LineActor [vtkActor New]
    $LineActor SetMapper $LineMapper
    [$LineActor GetProperty] SetColor 1.0 0.0 0.0

ren1 AddActor $LineActor

Thank in advance.
