Library that helps to implement the QuadTree in android, by using splitting images

Download via Gradle:

compile 'com.github.slavakyrai:quadtreeandroidimpl:0.1.1'

or Maven:

<dependency>
 <groupId>com.github.slavakyrai</groupId>
 <artifactId>quadtreeandroidimpl</artifactId>
 <version>0.1.1</version>
 <type>pom</type>
</dependency>

Create an instance of the QuadSplitter class. Pass the bitmap and OnQuadTreeSplitComplete callback in the constructor. The result will be returned as list of QuadTreeRect, in another thread in onSplitComplete().Use the method start() to start splitting image.

QuadTreeSplitter quadTreeSplitter = new QuadTreeSplitter(mutableBitmap, new OnQuadTreeSplitComplete() {
 @Override
 public void onSplitComplete(List<QuadTreeRect> quadTreeRects) {
 Log.d(TAG, "onSplitComplete: " + quadTreeRects.size());
 }
 });
quadTreeSplitter.start();

You can customize the work of the QuadSplitter class by using methods setMinQuadAreaSize() and setMinColorDistance().

quadTreeSplitter.setMinQuadAreaSize(50);
quadTreeSplitter.setMinColorDistance(5);

If you want to display the separeting image process, use the QuadTreeImageView class, which is extended by the ImageView. For than you must use the next methods: setImageBitmap() method of the QuadTreeImageView class, and setOnQuadDrawListener() method of the QuadTreeSplitter class. You can enable or disable the outlines of the rectangles borders, when you use the setDrawGreed() method.

QuadTreeImageView imageView = (QuadTreeImageView) findViewById(R.id.qtImgView);
imageView.setImageBitmap(mutableBitmap);
quadTreeSplitter.setOnQuadDrawListener(imageView);
imageView.setDrawGreed(true);
