# transformStruct

The matrix coefficients stored as the transformation matrix.

## Declaration

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

## Discussion

Discussion The matrix is of the form shown in Transform Mathematics, and the six-element structure defined by the NSAffineTransformStruct structure is of the form: {m11, m12, m21, m22, tX, tY} The NSAffineTransformStruct structure is an alternate representation of a transformation matrix that can be used to specify matrix values directly.
