When applying transforms ImageView fitWidth and fitHeight are calculated based on integer values. This causes large size jumps when the applied transformations map to a smaller coordinate space. For example use the following transform to create a coordinate space mapping 1024x768 to 120x90:

myTransform = [Scale{ x: 1024/120, y: 768/90 }, Translate{ 0, 0 }]

In my case I have the ImageView within a custom node:

class Custom extends CustomNode {
    public var content : Node;

    override protected function create() : Node {
        return content;
    }
}

Now let's create an ImageView with this:

var myNode : Custom = Custom {
  content: ImageView {
    image: myImg
    preserveRatio: false
    fitWidth: 7.5
    fitHeight: 7.5
  }
}

When adding this to a scene it should produce an image with 64x64 pixel size, however, it does not as the transform seems to be calculated based on the integer value 7 not 7.5.

The attached picture shows the too small image and a rectangle underneath it dimensioned with the proper size- using the same transform.
