# vImage_CGAffineTransform

A structure for values that represent a Core Graphics–compatible affine transformation.

## Declaration

```swift
typealias vImage_CGAffineTransform = vImage_AffineTransform_Double
```

## Mentioned in

Applying geometric transforms to images

## Discussion

Discussion This structure represents the 3x2 matrix :

This structure changes size to be the same size as the Core Graphics CGAffineTransform data structure. CGAffineTransform describes functions for creating and manipulating matrixes of this form.
