<commit_before># AKImageCropper

A View subclass for image cropping for iSO devices with support for landscape orientation. Cropper allows to specify the location and size of the crop frame. Easy to set up. Has many settings for flexible integration into your project. The plugin is written in Swift.

**Features:**

* Easy to set up and use
* Crop frame animation
* Full image resolution
* Zoom and scroll
* Сolor customization
* Action callbacks

## Usage

### Storyboard

```swift
@IBOutlet weak var cropView: AKImageCropperView!

override func viewDidLoad() {
    super.viewDidLoad()

    cropView.image = UIImage(named: "yourImage")
}

override func viewWillLayoutSubviews() {
    super.viewWillLayoutSubviews()

    // Refreshing
    cropView.refresh()
}
```

### Programmatically

```swift
var cropView: AKImageCropperView!

override func viewDidLoad() {
    super.viewDidLoad()

    let image = UIImage(named: "yourImage")
    let frame = CGRectMake(0, 0, 300, 300)
    cropView = AKImageCropperView(frame: frame, image: image, showCropFrame: false)

    view.addSubview(cropView)
}

override func viewWillLayoutSubviews() {
    super.viewWillLayoutSubviews()

    // Refreshing
    cropView.refresh()
}
```

## Initializing

```swift
init(frame: CGRect, image: UIImage, showCropFrame: Bool)
```

| Parameters  |  Description |
| ------------- | ------------- |
| frame         | The frame rectangle for the cropper view, measured in points. The origin of the frame is relative to the superview in which you plan to add it. |
| image         | The image you want to crop. The minimum size of the image is calculated by the formula: minWidth x minHeight = fingerSize*2 x fingerSize*2, where fingerSize - a size width of finger touch (default 30 px). |
| showCropFrame | Pass true to show crop frame on initialization. |

Initializes and returns a newly allocated croper view object with the specified frame rectangle, image to crop and crop frame show/hide on initialization flag.

## Properties

### Configuring

```swift
var image: UIImage?
```

The image you want to crop. The minimum size of the image is calculated by the formula: minWidth x minHeight = fingerSize*2 x fingerSize*2, where fingerSize - a size width of finger touch (default 30 px).
The initial value of this property is `nil`.

`var fingerSize: CGFloat`

A size width of finger touch on the outside line of crop frame. This value used to calculate a size of the outer offset crop frame. See diagram below.
```swift
//     __ __ __ __ Crop View __ __
//    |
//    |      __ __ __ __ Crop Frame __ __
//    |     |
//    |<--->| -- Offset fingerSize / 2 (Default: 15.0)
//    |     |
//    |<---- ----> -- Finger touch size "fingerSize"  (Default: 30.0)
//    |     |
```
The initial value of this property is `30` pixels.

`var cropFrameAnimationDuration: NSTimeInterval`

The duration of the transition animation, measured in seconds.
The initial value of this property is `300` milliseconds.

`var cropFrameAnimationOptions: UIViewAnimationOptions`

Specifies the supported animation curves.
The initial value of this property is `CurveLinear`.<commit_msg>Documentation<commit_after># AKImageCropper
