## Declaration

static func affineFit(source: CGSize, sourceOrientation: UIInterfaceOrientation, target: CGSize, targetOrientation: UIInterfaceOrientation) -> CGAffineTransform

#### Summary

Returns an affine transformation that maps normalized coordinates in the source frame to normalized coordinates in the target frame.

#### Returns

An affine transformation matrix that fits the source into the target.

> **Info:**
>
> **Notice**
>
> Note: In portrait, this function aligns the top and bottom edges to the target.
