Thanks for the links, I'll take a look. Rob

Then I would like to see a size of 150x150 pixels and still see a sharp border stroke, let's say with a width of 2 pixels. I'm not sure how I could apply a snapping transformation to just correct stroke widths and not disturb the size of the shapes themselves.

Juni 2014 11:42 An: openjfx-dev@openjdk.java.net Betreff: Re: Blurry strokes and zooming via scale transforms I recently had a similar situation, but then because certain properties were calculated-via-binding and the resulting value was not "snapped" to good values either. This resulted in my suggestion to allow custom calculations in bindings, which would then snap the value. https://javafx-jira.kenai.com/browse/RT-37255 And transformations on such values have the same effect of course. I was wondering, similar to the binding suggestion, would it be possible to apply a snapping transformation as the last transformation?
