## API Reference

### captureRemoteDocument

> Source set: Android

```kotlin
public fun captureRemoteDocument(
    context: Context,
    creationDisplayInfo: RemoteCreationDisplayInfo,
    remoteDensity: RemoteDensity =
        RemoteDensity(
            creationDisplayInfo.density.density.rf,
            creationDisplayInfo.density.fontScale.rf,
        ),
    layoutDirection: LayoutDirection? = null,
    writerEvents: WriterEvents = WriterEvents(),
    clock: RemoteClock = RemoteClock.SYSTEM,
    profile: Profile = RcPlatformProfiles.ANDROIDX,
    coroutineContext: CoroutineContext = Dispatchers.Default,
    content: @Composable @RemoteComposable () -> Unit,
): Flow<ByteArray>
```

Capture a stream of RemoteCompose documents by rendering the specified `content` Composable in a
virtual display and emitting the resulting byte arrays whenever recomposition occurs and the
layout visually changes.

This API allows capturing dynamic Compose content (e.g., containing animations, transitions, or
state updates) as a Flow of serialized document byte arrays.

Crucially, recomposition is handled cleanly, and duplicate documents (where nothing visually
changed in the layout tree) are automatically filtered out, so new byte arrays are only emitted
when the document actually changes.

#### Parameters

| | |
| --- | --- |
| creationDisplayInfo | Details about the virtual display to capture for (size, density, etc.). |
| remoteDensity | The logical screen density and font scale to use for unit conversions. Defaults to density derived from `creationDisplayInfo`. Note: If passing custom values, they should typically match the density and font scale specified in `creationDisplayInfo` to avoid layout scaling discrepancies. |
| layoutDirection | The layout direction (LTR or RTL) to use. Defaults to LTR. |
| writerEvents | Callback to handle non-serializable events (e.g. pending intents). |
| context | The Android [Context](https://developer.android.com/reference/android/content/Context) to use. |
| clock | The clock used for the recomposer timeline. Defaults to `RemoteClock.SYSTEM`. |
| profile | The writing profile that determines supported operations. Defaults to `RcPlatformProfiles.ANDROIDX`. |
| coroutineContext | The CoroutineContext to run recomposition and rendering on. Defaults to `Dispatchers.Default`. |
| content | The Composable content to render and capture. |

#### Returns

| | |
| --- | --- |
|  | A `Flow` of `ByteArray`s containing the serialized RemoteCompose documents. |
