Artifact: [androidx.ink:ink-storage](https://developer.android.com/jetpack/androidx/releases/ink) [View Source](https://cs.android.com/search?q=file:androidx/ink/storage/BrushFamilyExtensions.kt+function:decode) Added in [1.1.0-alpha11](https://developer.android.com/jetpack/androidx/releases/ink#1.1.0-alpha11)

```
@Throws(exceptionClasses = [IOException])
public static final @NonNull BrushFamily decode(
    @NonNull BrushFamily.Companion receiver,
    @NonNull byte[] input,
    @NonNull Version maxVersion,
    OnDecodeTexturePngBytes onDecodeTexture

```

Read a serialized `https://developer.android.com/reference/androidx/ink/brush/BrushFamily` from the given `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-byte-array/index.html` and parse it into a `https://developer.android.com/reference/androidx/ink/brush/BrushFamily`, throwing an exception if parsing or validation was not successful.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull byte[] input` | `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-byte-array/index.html` providing gzip-compressed `ink.proto.BrushFamily` binary proto messages, the same as written by `https://developer.android.com/reference/androidx/ink/storage/package-summary#(androidx.ink.brush.BrushFamily).encode(androidx.ink.storage.TexturePngBytesLookup)`. |

This is called synchronously as part of this function call, on the same thread, once for each texture image. |

| Returns |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/ink/brush/BrushFamily` | The `https://developer.android.com/reference/androidx/ink/brush/BrushFamily` parsed from the `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-byte-array/index.html`. |

| `https://developer.android.com/reference/androidx/ink/storage/IOException` | if gzip-format bytes cannot be read from `https://developer.android.com/reference/androidx/ink/storage/package-summary#(androidx.ink.brush.BrushFamily.Companion).decode(kotlin.ByteArray,androidx.ink.brush.Version,androidx.ink.storage.OnDecodeTexturePngBytes)`. |

    TexturePngBytesLookup textureIdToPngBytes
)
```

Write a gzip-compressed `ink.proto.BrushFamily` binary proto message representing the `https://developer.android.com/reference/androidx/ink/brush/BrushFamily` to the given `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-byte-array/index.html` using the provided callback to retrieve texture PNG bytes. If `https://developer.android.com/reference/androidx/ink/brush/BrushFamily#hasFallbacks()` is true, then the stored proto message including fallbacks for this `https://developer.android.com/reference/androidx/ink/brush/BrushFamily` will be used instead of recomputing the proto from the `https://developer.android.com/reference/androidx/ink/brush/BrushFamily` object.
