Hello again,<br><br>So I have tried hard to get this vtkImageActor to show on the screen. I have another image and I am trying to draw on top of that image:<br><br>So, I have the following:<br><br>// overlayImage is a PNG image
<br><br>actor = vtkImageActor::New();<br>actor->SetInput(overlayImage->GetOutput());<br>actor->PickableOn();<br>actor->SetDisplayExtent(0, im_width, 0, in_height, 0, 0);
<br>actor->SetPosition(0, 0, 0);<br><br>Now what happens is that the whole screen goes black! My image is only 200, 200 and I want it to show over another image. How do I get it working?<br><br>Thanks!<br>
