Rendering to a Bitmap

Render screenshots and video at runtime.

Rendering to a bitmap at runtime is useful for scenarios such as snapshot testing and rendering video encoded from data-bound files.

For rendering to a bitmap from the Rive Editor, see Exporting for Video or Static Design.

Compose

Demo

See the RiveSnapshotActivity example for a demonstration of this feature.

Rendering to a bitmap is done using the RenderBuffer class or the onBitmapAvailable callback in the Rive Composable.

Legacy

Rendering to a bitmap was technically possible in the legacy runtime by rendering to a Canvas backed by a bitmap or by sub-classing the renderer, but it was not a built-in feature and required more effort to implement. There are no plans to retrofit this feature into the legacy runtime.
