# components

Return a pointer to an array of CGFloat values including alpha.

## Declaration

```swift
var components: UnsafePointer<CGFloat> { get }
```

## Discussion

Discussion Typically this array will contain 4 CGFloat values for red, green, blue, and alpha. If the CIColor was initialized with a CGColor then returned pointer will be the same as calling CGColorGetComponents()
