<DIV> Hi,</DIV>
<DIV> </DIV>
<DIV>Sorry to bother you again. </DIV>
<DIV> </DIV>
<DIV>I tried what you indicated me to scale my image into a window I passed.</DIV>
<DIV> </DIV>
<DIV><STRONG>I have no error at compilation. However, my image is not scaled at execution. </STRONG></DIV>
<DIV> </DIV>
<DIV>Is there any fault in this code:</DIV>
<DIV> </DIV>
<DIV>viewer->SetInput(reader->GetOutput());</DIV>
<DIV> </DIV>
<DIV> <STRONG>vtkRenderer* ren1 = viewer->GetRenderer();<BR> ren1->GetActiveCamera()->ParallelProjectionOn(); <BR>ren1->GetActiveCamera()->SetParallelScale(0.5);</STRONG></DIV>
<DIV> </DIV>
<DIV> //display the image in the frame<BR> viewer->SetParentId(this->m_hWnd);</DIV>
<DIV> </DIV>
<DIV> //execute<BR> viewer->Render(); </DIV>
<DIV> </DIV>
<DIV>thanks in advance, </DIV>
<DIV> </DIV>

It works well, but my image is<BR>still displayed with its own dimensions. What I would like to do is find a<BR>way to display it in order to fit the dimensions of my window, something<BR>which could stretch my image.<BR><BR>Could someone suggest me something?
