Detailed Description

Interface for intercepting pre-composed layer creation.

Embedders can register interceptors with animation builders, to substitute target layers with arbitrary/externally-controlled content (see ExternalLayer above).

Member Function Documentation

onLoadPrecomp()

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

pure virtual

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).

Implemented in skottie_utils::ExternalAnimationPrecompInterceptor.
