Detailed Description

A sample PrecompInterceptor implementation.

Attempts to substitute all precomp layers matching the given pattern (name prefix) with external Lottie animations.

◆ onLoadPrecomp()

sk_sp< skottie::ExternalLayer > skottie_utils::ExternalAnimationPrecompInterceptor::onLoadPrecomp	(	const char	id[],
		const char	name[],
		const SkSize &	size
	)

overrideprivatevirtual

Invoked at animation build time, for each precomp layer.

Parameters

id	The target composition ID (usually assigned automatically by BM: comp_0, ...)
name	The name of the precomp layer (by default it matches the target comp name, but can be changed in AE)
size	Lottie-specified precomp layer size

Returns: An ExternalLayer implementation (to be used instead of the actual Lottie file content), or nullptr (to use the Lottie file content).

Implements skottie::PrecompInterceptor.
