# viewport

The portion of the texture that the view uses to draw its content.

## Declaration

```swift
var viewport: MTLViewport { get }
```

## Discussion

Discussion This retrieves the size of the view and its location within the texture. If the layer dedicates a separate texture to each view, the texture bounds and view bounds match. However, if the layer uses a shared or layered texture, the view’s location or other slice index might differ.
