ok answering my own question it is quite simple using
setFitWidth/setFitHeight already today.
ImageView renderingView ....
renderingView.setFitWidth(width / scaleFactor);
renderingView.setFitHeight(height / scaleFactor);
I already tested that before sending out this mail but unfortunately it
did not work because I had a reflection effect on the parent node and it
took the whole day to track down that I run a bug with the
Reflection-Effect I documented at [1].

Hi,
I'm try to get a HiDPI-Image produced by an external application into
JavaFX using WritableImage.
In the end the situation is comparable to what you get today when
loading an image from an URL (eg sam...@2.png) where JavaFX sets the
appropriate image pixelScale on "com.sun.prism.Image".
If I'm not completely mistaken I would need an new API on PixelBuffer to
containing the pixelScale who is used QuantumImage to create an
appropriate "com.sun.prism.Image" who has eg the pixelScale = 2.0
because I fed in a HiDPI-Image already.
Before filing an ehancement I wanted to bring this up here because maybe
I'm missing something obvious or maybe my proposal makes totally no sense.
