Scaling images in JavaFX - javafx-2

Question

I am using ImageViewBuilder to create an ImageView and I need to test the properties preserveRatio , fitWidth and fitheight
I was looking at the docs and still cannot figure out how to.
Help will be appreciated. Here is my code (not SSCCE)
ImageView img = ImageViewBuilder
.create()
.image(new Image("http://projavafx.com/images/earthrise.jpg")) // path to image
.build();
If someone could please update the code to show me how to use the fitHeight() and fitWidth() methods then that would be highly appreciated.

Answer 1

IT is not entirely clear what you are trying to do. To use the fitWidth/fitHeight/preserveRatio properties, you can either use the get/set.. methods or,
ImageView img = ImageViewBuilder
.create()
.image(new Image("http://projavafx.com/images/earthrise.jpg")) // path to image
.build();
img.setFitHeight(value); // or getFitHeight() if that is what you need.
img.setFitWidth(value); // or getFitWidth() if that is what you need.
img.preserveRatioProperty(true); // or isPreserveRation() if that is what you need.
or alternatively, access the properties and then call the get/set methods on those:
img.fitHeightProperty().set(value);
img.fitWidthProperty().set(value);
img.preserveRatioProperty().set(true);
This is pretty basic. If you put more information about what exactly the problem is, then you might get a more specific and less basic answer.
