Subject: Re: [vtkusers] Help for copy of vtkImageData<br>To: John Drescher <<a href="mailto:drescherjm@gmail.com">drescherjm@gmail.com</a>><br><br><br>Hi, John :<br><br>My code is <br><br>// Map the image through the lookup table<br>
vtkSmartPointer<vtkImageMapToColors> color = vtkSmartPointer<vtkImageMapToColors>::New();<br> color->SetLookupTable(table);<br>
color->SetInputConnection(reslice->GetOutputPort());<br><br> m_imgDataOnImagePlaneX->DeepCopy(color->GetOutput());<br><br>These code are in a class member function, and m_imgDataOnImagePlaneX is a class member variable. I used vtkImageViewer2 to display the image data from m_imgDataOnImagePlaneX, but nothing is on the VTK window. However, when I used vtkImageViewer2 to display the image data from color->GetOutput() in that class member function, that is ok. I don't know why.<div>

<div>> In my programming, I want to copy a local variable of vtkImageData to a global variable of vtkImageData, and I tried shallowcopy and deepcopy, but they didn't work. Does anyone have ideas about this problem?<br>

<br>
</div>Nope. DeepCopy has always worked for me. Please post a small example<br>
demonstrating the problem.<br>
