# isBlendingEnabled

A Boolean value that determines whether blending is enabled.

```
var isBlendingEnabled: Bool { get set }
```

## Discussion

The default value is <doc://com.apple.documentation/documentation/Swift/false>, meaning blending is disabled and pixel values are unaffected by blending. Disabled blending is effectively the same as the `MTLBlendOperationAdd` blend operation with a source blend factor of `1.0` and a destination blend factor of `0.0` for both RGB and alpha.

If the value is <doc://com.apple.documentation/documentation/Swift/true>, blending is enabled and the blend descriptor property values are used to determine how source and destination color values are combined.
