# Rasterization for fixing offscreen rendering

To fix offscreen rendering issues in overlap containers, use the `rasterize` extension (iOS only):

```json translate=no
{
  "extensions": [
    {
      "id": "rasterize"
    }
  ]
}
```

The extension has no parameters.

## How it works {#behavior}

- The element together with its nested elements is rendered as a single bitmap image.
- The image is created at the pixel density of the screen, so the content stays sharp.
- Solves offscreen rendering issues in overlap containers.

## Connection {#connect}

```swift translate=no
DivKitComponents(
  ...
  extensionHandlers: [
    RasterizeExtensionHandler()
  ]
)
```
