Hi Stephane, On the VTK side which might be able to be done in the scripting layer of ParaView also (but not sure), you will need 2 things:
1) tell the render window to send alpha : view->GetRenderWindow()->SetAlphaBitPlanes(1); 2) request the Alpha value on the window capture filter : this->WindowCapture->SetInputBufferTypeToRGBA(); And if you write a PNG image, the background will be transparent.
