Found the problem, SetPosition was needing coordinated in pixel but
SetPosition2 in normalized format.<br>
So with this code now it works:<br>
<br>
ImageActor->GetPositionCoordinate()->SetCoordinateSystemToNormalizedViewport();<br>
ImageActor->GetPosition2Coordinate()->SetCoordinateSystemToNormalizedViewport();<br>
ImageActor->SetPosition(0.25,0.25);<br>
ImageActor->SetWidth(0.5);<br>
ImageActor->SetHeight(0.4);<br>
<br>
Regards<br>

Hi<br>
I need to display an image in a part of the screen.<br>
I'm using the chain:<br>
vtkImageImport->vtkImageMapToColors->vtkImageMapper->vtkActor2D->vtkRenderer<br>
<br>
I have set Position and Position2 of vtkActor2D to set the image
box.<br>
<br>
It looks is not enough...<br>
<br>
So I set vtkImageMapper::RenderToRectangleOn() hoping for a
solution, but only Position2 is rightly imported, the image starts
always from (0,0) (any 'Position' looks ignored)<br>
<br>
[I check into vtkImageMapper.cxx and the flag RenderToRectangle is
never used...this is also strange...]<br>
<br>
Any help?<br>
Thank you
