public class CropSquareTransformation implements Transformation {

  private int mWidth;
  private int mHeight;

  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(source.getWidth(), source.getHeight());

    mWidth = (source.getWidth() - size) / 2;
    mHeight = (source.getHeight() - size) / 2;

    Bitmap bitmap = Bitmap.createBitmap(source, mWidth, mHeight, size, size);
    if (bitmap != source) {
      source.recycle();
    }

    return bitmap;
  }

  @Override public String key() {
    return "CropSquareTransformation(width=" + mWidth + ", height=" + mHeight + ")";
  }
