Hi David,
I have a possible fix for the failing
tracer widget test:
here is what works for the tcl example:
#------------------------
vtkLinearExtrusionFilter extrude
extrude SetInput spoly
extrude SetScaleFactor 1
extrude SetExtrusionTypeToNormalExtrusion
extrude SetVector 1 0 0
# help the stencil out a but by forcing the
# polydata to straddle the image plane
#
vtkTransformPolyDataFilter filter
vtkTransform trans
trans Translate -0.5 0 0
filter SetInput [extrude GetOutput]
filter SetTransform trans
vtkPolyDataToImageStencil dataToStencil
dataToStencil SetInputConnection [filter GetOutputPort]
# have to set the image information somehow
#
dataToStencil SetInformationInput [extract GetOutput]
#------------------------
although when I use the SetInformationInput method
I get a slew of leaks from vtkDebugLeaks. If I use
the SetOutputOrigin, SetOutputSpacing,
SetOutputWholeExtent methods, the leaks do not
occur. Could you verify that leaks occur if you
use the former method?
