[vtk-developers] vtkImageCast bug #0011193

[Lodron, Gerald]

Hi

While writing a simple void main application i found the error, lol. It seems that the GetOutput() does not call an update():

   vtkSmartPointer<vtkImageCast> oInputCaster1 = vtkImageCast::New();
    oInputCaster1->ReleaseDataFlagOn();
    oInputCaster1->SetInput(oInput1);

    oInputCaster1->GetOutput()->Print(std::cout);	//no update is called, origin is 0,0,0!
    oInputCaster1->Update();
    oInputCaster1->GetOutput()->Print(std::cout);	//now origin is correct

Is it correct that no update on GetOutput() is called?

Gerald,

I looked at the source for ImageCast and it should be maintaining the origin. I modified a small example and I cannot repeat the problem.
Can you provide a small compilable example that illustrates the issue?

Bill
