<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>No, I'm not. I'm want to display a 2D image. So I presume that I don't have to use <STRONG>SetZSlice</STRONG>(). If so, why should I? </DIV>
<DIV> </DIV>
<DIV>Here is my code:</DIV>
<DIV> </DIV>
<DIV><STRONG>viewer->SetInput(image2D);</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> //display the image in the frame<BR> viewer->SetParentId(this->m_hWnd);</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> //to fit the image to the render window, <BR> //parallel camera = parallel projection is used <BR> vtkRenderer* ren1 = viewer->GetRenderer(); <BR> ren1->GetActiveCamera()->ParallelProjectionOn(); <BR> ren1->GetActiveCamera()->SetParallelScale(0.5);</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> //execute<BR> viewer->Render(); </STRONG></DIV>
<DIV> </DIV>
