# isOpaque

A Boolean that indicates whether the canvas is fully opaque.

## Declaration

```swift
nonisolated var isOpaque: Bool { get set }
```

## Discussion

Discussion You might be able to improve performance by setting this value to true, making the canvas is fully opaque. However, in that case, the result of drawing a non-opaque image into the canvas is undefined.
