[vtk-developers] RE: Problem when creating vtkImageData by hand

[Dean Inglis]

Hi Prabhu,

I tried this in c++ based on Widgets/Testing/Cxx/ImagePlaneWidget.cxx
but created the copy like this 

  vtkImageData* my_img_data = vtkImageData::New();
  my_img_data->ReleaseDataFlagOff();
  my_img_data->CopyStructure( img_data );
  my_img_data->CopyAndCastFrom( img_data, img_data->GetWholeExtent() );
  my_img_data->SetUpdateExtentToWholeExtent();
  my_img_data->Update();

  vtkImgeData* img_data =  my_img_data;

and removed the outline filter from the pipeline
and everything runs fine.  As soon as
I add the outline filter, I get the same
weird results.  I haven't figured out if
this is a pipeline problem, IPW problem or outline
filter pb.... :{
