Add support for rendering drop shadows #2142

calda · 2023-08-15T22:20:11Z

This PR adds support for rendering drop shadows using the Core Animation rendering engine. Fixes #1169.

There are two different JSON schema representations for drop shadows. The most common option is the "layer effects" schema, but there's also a second "layer style" schema. This PR adds support for both.

`DropShadowEffect`

`DropShadowStyle`

+      //  - `softness=50` roughly corresponds to `cornerRadius=6.25`
+      // This could probably be improved with more examples.
+      let x = softnessValue.cgFloatValue
+      let cornerRadiusMapping = (-0.003 * pow(x, 2)) + (0.281 * x)


Worked with Remington to get this to match the preview in After Effects. For example:

Start, iOS End, iOS

Start, After Effects End, After Effects

This was the only mapping I could find that we thought looked right in both of these cases

Sources/Private/CoreAnimation/Animations/LayerProperty.swift

+  static var shadowOffset: LayerProperty<CGSize> {
+    .init(
+      caLayerKeypath: #keyPath(CALayer.shadowOffset),
+      defaultValue: CGSize(width: 0, height: -3.0),


why does this and shadowRadius have non-zero default values?

This is the default value of the CALayer.shadowOffset property (documentation):

The default value of this property is (0.0, -3.0).

Knowing this value lets us apply certain optimizations in the code that generates the CAKeyframes. (e.g. if the Lottie animation just sets the property to the default value, we can completely omit the keyframes and reduce the overhead of computing the keyframes)

ah great, this might be a good comment to add in code here so others aren't confused in the future!
