## Public constructors

### Builder

```
public Builder(Context context)
```

Creates a builder.

| Parameters |
|---|---|
| `https://developer.android.com/reference/android/content/Context.html context` | The context. |

## Public methods

### build

```
public DataSourceBitmapLoader build()
```

Builds a `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader`.

### setBitmapFactoryOptions

```
@CanIgnoreReturnValue
public DataSourceBitmapLoader.Builder setBitmapFactoryOptions(@Nullable BitmapFactory.Options options)
```

Sets the `https://developer.android.com/reference/android/graphics/BitmapFactory.Options.html` to be used for decoding bitmaps.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://developer.android.com/reference/android/graphics/BitmapFactory.Options.html options` | A `https://developer.android.com/reference/android/graphics/BitmapFactory.Options.html`. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader.Builder` | This builder. |

### setDataSourceFactory

```
@CanIgnoreReturnValue
public DataSourceBitmapLoader.Builder setDataSourceFactory(DataSource.Factory dataSourceFactory)
```

Sets the `https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory` to be used to create `https://developer.android.com/reference/androidx/media3/datasource/DataSource` instances for loading bitmaps.

If not set, a `https://developer.android.com/reference/androidx/media3/datasource/DefaultDataSource.Factory` will be used.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory dataSourceFactory` | A `https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory`. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader.Builder` | This builder. |

### setExecutorService

```
@CanIgnoreReturnValue
public DataSourceBitmapLoader.Builder setExecutorService(ListeningExecutorService listeningExecutorService)
```

Sets the `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListeningExecutorService.html` to be used for loading bitmaps.

If not set, `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader#DEFAULT_EXECUTOR_SERVICE()` will be used.

| Parameters |
|---|---|
| `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListeningExecutorService.html listeningExecutorService` | A `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListeningExecutorService.html`. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader.Builder` | This builder. |

### setMakeShared

```
@CanIgnoreReturnValue
public DataSourceBitmapLoader.Builder setMakeShared(boolean makeShared)
```

Sets whether the `https://developer.android.com/reference/android/graphics/Bitmap.html` should be converted to an immutable, sharable instance that is most efficient for repeated transfer over binder interfaces.

| Parameters |
|---|---|
| `boolean makeShared` | Whether to make the `https://developer.android.com/reference/android/graphics/Bitmap.html` shared. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader.Builder` | This builder. |

| See also |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/BitmapUtil#makeShared(android.graphics.Bitmap)` |   |

### setMaximumOutputDimension

```
@CanIgnoreReturnValue
public DataSourceBitmapLoader.Builder setMaximumOutputDimension(int maximumOutputDimension)
```

Sets the maximum output dimension for decoded bitmaps.

The decoder downscales the image using power-of-2 `inSampleSize` (subsampling) until the larger dimension is less than or equal to the maximum output dimension.

Note: Because only power-of-2 scaling is supported during decoding, the returned bitmap can be significantly smaller than the requested maximum output dimension if the original size is just above the limit (e.g. decoding a 1080px image with a 900px limit results in a 540px image). If you need the bitmap to be scaled closer to the limit, you may need to post-process the decoded bitmap or wrap this loader in a custom loader that performs precise scaling.

| Parameters |
|---|---|
| `int maximumOutputDimension` | The maximum output dimension in pixels. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/DataSourceBitmapLoader.Builder` | This builder. |
