PR Type

What kind of change does this PR introduce?

  • Optimization

What is the current behavior?

All Visual objects created through our pipeline system are kept in sync with target objects through an expression animation.

What is the new behavior?

We're now just using Visual.RelativeSizeAdjustment to achieve the same without the animation overhead.

I did test this in the sample app, but still adding the testing required tag as I'd like more validation on this.

Open questions

I'm wondering whether there's a way to also optimize this bit here by removing the animation:

Vector2 center = newValue.ToVector2();
Visual visual = element.GetVisual();
const string expression = "Vector2(this.Target.Size.X * X, this.Target.Size.Y * Y)";
ExpressionAnimation animation = visual.Compositor.CreateExpressionAnimation(expression);
animation.SetScalarParameter("X", center.X);
animation.SetScalarParameter("Y", center.Y);
visual.StopAnimation("CenterPoint.XY");
visual.StartAnimation("CenterPoint.XY", animation);

Haven't yet figured out a solution though 🤔

EDIT: spoke with Chris, yeah there isn't a way to do this, nevermind 🤣

Ah, I was confused by the change of Visual from CompositionObject, but it's on an internal extension, so we're fine.
