Member Function Documentation

onRenderFrame()

abstract void org.skia.jetski.util.SurfaceRenderer.onRenderFrame ( Canvas  canvas, long  ms  )

abstractprotected

Callback for frame content.

Invoked once per (vsync'ed) frame.

Reimplemented in org.skia.jetski.util.SkottieRenderer, org.skia.jetskidemo.AnimationRenderer, org.skia.jetskidemo.CubeRenderer, org.skia.jetskidemo.MainActivity.DemoRuntimeShaderRenderer, org.skia.jetskidemo.RuntimeShaderRenderer, and org.skia.jetskidemo.SkottieAnimationRenderer.

onSurfaceInitialized()

abstract void org.skia.jetski.util.SurfaceRenderer.onSurfaceInitialized ( Surface  surface )

abstractprotected

Initialization callback.

This can be invoked multiple times if the underlying surface changes.

Reimplemented in org.skia.jetski.util.SkottieRenderer, org.skia.jetskidemo.AnimationRenderer, org.skia.jetskidemo.CubeRenderer, org.skia.jetskidemo.MainActivity.DemoRuntimeShaderRenderer, org.skia.jetskidemo.RuntimeShaderRenderer, and org.skia.jetskidemo.SkottieAnimationRenderer.
