Hi Chris,<div><br></div><div>The SetUpdateExtent() method is a vtkImageData method, not a</div><div>vtkImageReslice method. I.e. you would call</div><div>reslice->GetOutput()->SetUpdateExtent(extent)</div><div>before calling Update(). This method has existed in vtkImageData</div>

First, thank you very much!<br>
<br>
I finally got them to change from Update() to UpdateWholeExtent(), and now<br>
everything works fine.<br>
The reason it happens is that we are using an old version of vtk. There is<br>
no SetUpdateExtent(), only SetOuputExtent(). So when SetOutputExtent() is<br>
called the first time, it effectively sets the update extent and whole<br>
extent to the same value. Then when SetOutputExtent() is called the second<br>
time with a smaller extent, it only sets the whole extent. As a result, the<br>
extent error occurs when Update() is called.<br>
<br>
Switching to UpdateWholeExtent() solves the problem. Thank you again!<br>
