# transformStruct

The matrix coefficients stored as the transformation matrix.

```
var transformStruct: NSAffineTransformStruct { get set }
```

## Discussion

The matrix is of the form shown in [Transform Mathematics](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/CocoaDrawingGuide/Transforms/Transforms.html#//apple_ref/doc/uid/TP40003290-CH204-BCIIICJI), and the six-element structure defined by the [`NSAffineTransformStruct`](/documentation/Foundation/NSAffineTransformStruct) structure is of the form:

```objc
{m11, m12, m21, m22, tX, tY}
```

The [`NSAffineTransformStruct`](/documentation/Foundation/NSAffineTransformStruct) structure is an alternate representation of a transformation matrix that can be used to specify matrix values directly.

[`init(transform:)`](/documentation/Foundation/NSAffineTransform/init(transform:))

Initializes the receiver’s matrix using another transform object.
