# destinationAlpha

Premultiplication description for the destination texture.

## Declaration

```swift
var destinationAlpha: MPSAlphaType { get }
```

## Discussion

Discussion Color space conversion operations produce non-premultiplied data. Use this property to tag cases where premultiplied results are required. If the MPSAlphaType.alphaIsOne value is used, the alpha channel will be set to 1. The default value is MPSAlphaType.alphaIsOne.
