I'm trying to capture an image that is in a vtkRenderWindow using vtkRenderLargeImage like the example above.
When I use renderLage.Update() in example above, an other window appear .
Why this occur ? I don't want this window opened.
Are There an error in vtkRenderLargeImage ?
I'm using :
vtk5... The last one in cvs.
python25
windows XP

------------------------------------------------Example (part of code) --------------------------------

previewRenderer = vtkRenderer
previewRenderer.AddActor2D(previewActor2D)
previewRenderer.AddActor2D(previewActorText)

previewRenderWindow = vtkRenderWindow()
previewRenderWindow.AddRenderer(previewRenderer)
previewRenderWindow.Render()

renderLarge = vtkRenderLargeImage()
renderLarge.SetInput(previewRenderer)
renderLarge.SetMagnification(1)
renderLarge.Update()
