I tried setSmooth but it doesn’t work.
See the doc: "Indicates whether to use a better quality filtering algorithm or
a faster”.
I expected this be a set for the interpolation algorithm (bilinear, bicubic,
nearest neighbor, etc).
My case I didn’t want a faster filter, I wanted no filter.
Anyway, looking at the code, at the rendering level, NSImageView:
// RT-18701: this method does nothing
public void setSmooth(boolean s) {}

For a workaround done outside JavaFX I can’t think of any other way.
I used this code snippet for a simple testing app, small images.
