smartcrop-android

smartcrop implementation in Java(Android)

This library will analyze best crop position and size by calculating some features; edge, skin tone, staturation and face.

original javascript version

Usage

With RxJava(+ RxAndroid)

SmartCrop
  .analyzeWithObservable(Options.newInstance().cropSquareSize(200), selectedImage)
  .subscribeOn(Schedulers.computation())
  .observeOn(AndroidSchedulers.mainThread())
  .subscribe(new Action1<CropResult>() {

@Override

public void call(CropResult cropResult) {

 // do what you want

}

  
}
);
 

Without Rx

But I recommend using RxJava or background thread because it took some times(about 500ms on 2013 Nexus5) so that it may stop the UI refresh and make bad UX.

// this code will block about 500ms CropResult cropResult = SmartCrop.analyze(Options.newInstance().cropSquareSize(200), selectedImage);
 

Output

CropResult.java

public class CropResult {

  public final Crop topCrop; // The best cropx, y, width, height and score
  public final List<Crop> crops; // crop candidates
  public final Bitmap debugImage;
  public final Bitmap resultImage; // cropped image from original image. Size is same with options.cropWidth/Height 
}
 

How to add dependency?

This library is not released in Maven Central, but instead you can use JitPack

add remote maven url

repositories {

  maven {

url "https://jitpack.io"
  
}
 
}

then add a library dependency

dependencies {

  compile 'com.github.QuadFlask:smartcrop-android:0.0.1' 
}

or, you can manually download aar and put into your project's libs directory.

and add dependency

dependencies {

  compile(name:'[arrFileName]', ext:'aar') 
}

check out [latestVersion] at releases

Features

skin, edge, staturation is almost same with javascript version. Android's face detection is used which draw white circle at face
