# vImage_AffineTransform_Double

A structure for values that represent a double-precision affine transformation.

## Declaration

```swift
struct vImage_AffineTransform_Double
```

## Overview

Overview This structure represents the 3x2 matrix :

In 64-bit applications, this structure is just like the Core Graphics CGAffineTransform data structure. In 32-bit applications, the Core Graphics data structure is equivalent to vImage_AffineTransform. Most of the time, you should use the vImage_CGAffineTransform data structure, which changes size depending on architecture. The CGAffineTransform describes functions for creating and manipulating matrixes of this form.
