## Overview

TinyCrayon SDK provides tools for adding image cutout and layer mask capabilities to your mobile applications.



Image layer mask is a fundamental technique in image manipulations. It allows you to selectively modify the opacity (transparency) of the layer they belong to. This flexibility to define the opacity of different areas of a layer is the basis for more interesting image manipulation techniques such as selective coloring and luminosity masking.



The current version of TinyCrayon SDK provides the following three tools:

* Quick Select: Smart and easy to use, users just need to select part of the object and the edge detection algorithm will find the boundary.

* Hair Brush: Smooth and natual looking, paint on the hair/fur of an object and the algorithm will select the hair/fur for you in high quality.

* Regular Brush: A regular brush tool with the capability to adjust its size, hardness and opacity.



## Features

* Free: TinyCrayon SDK is provided under MIT license, you can use it in your commercial applications for free!

* iPad support: TinyCrayon SDK uses auto layout for its views and adapts to each screen size - iPhone or iPad.

* Highly customizable: Style the UI, view modes and localized languages as you wish.

* Swift: Keeping up with time, we chose Swift as the main development language of the TinyCrayon SDK, leading to leaner easier code.

* Objective-C support: All of our public API is Objective-C compatible.

## Installation



### Prerequisites

* Xcode 9.0 or later.

* A physical iOS device.



### Steps

1. Git clone this repo

2. Download [OpenCV2](https://opencv.org/releases/) for iOS pack

3. Unzip opencv-xxx.zip, move *opencv2.framework* to TCCore folder

4. Open your project, drag *TinyCrayon.xcodeproj* to your workspace, then add *TCMask* to *Frameworks, Libraries, and Embeded Content* in your target->General settings



### Settings for Objective-C



If your project is using Objective-C, set `Always Embed Swift Standard Libraries` to be YES in your Build Settings.



## Usage



### Add a TCMaskView



The `TCMaskView` class is responsible to create a `UIViewController` for the user to mask the image.

To present a `TCMaskView`:



*Swift*

```

let maskView = TCMaskView(image: image)

maskView.delegate = self

maskView.presentFrom(rootViewController: self, animated: true)

```

*Objective-C*

```

TCMaskView *maskView = [[TCMaskView alloc] initWithImage:image];

maskView.delegate = self;

[maskView presentFromRootViewController:self animated:true];

```



The delegate of the `TCMaskView` can be used to be notified when the user cancels or completes the edit. In last case the function `tcMaskViewDidComplete(mask:image:)` is called. 



### TCMask class



`TCMask` is provided by `TCMaskViewDelegate` functions as the first parameter when the user cancels or completes the edit. For example, when the user completes the edit with `TCMaskView`:



*swift*

```

func tcMaskViewDidComplete(mask: TCMask, image: UIImage) {}

```

*Objective-C*

```

- (void)tcMaskViewDidCompleteWithMask:(TCMask *)mask image:(UIImage *)image {}

```



`TCMask` is an encapsulation of image masking result from `TCMaskView`, it has the following properties:



* data: An array of 8-bits unsigned char, its length is equal to the number of pixels of the image in `TCMaskView`. Each element in data represents the mask value.

* size: The size of mask, which is equal to the size of the image in `TCMaskView`.



`TCMask` also provides some simple and easy to use functions to process layer mask with image. For example, to cutout an object:



*Swift*

```

let outputImage = mask.cutout(image: image, resize: false)

```

*Objective-C*

```

UIImage *outputImage = [mask cutoutWithImage:image resize:false];

```



To try these examples, and find out about more options please take a look at the [Examples](https://github.com/TinyCrayon/TinyCrayon-iOS-SDK/releases).
