/**
 * @param bitmap     bitmap to blur
 * @param blurRadius blur radius (1..25)
 * @return blurred bitmap
 */
@Override
public final Bitmap blur(Bitmap bitmap, float blurRadius) {
  //Allocation will use the same backing array of pixels as bitmap if created with USAGE_SHARED flag
  Allocation inAllocation = Allocation.createFromBitmap(renderScript, bitmap);
  if (!canReuseAllocation(bitmap)) {
    if (outAllocation != null) {
      outAllocation.destroy();

    outAllocation = Allocation.createTyped(renderScript, inAllocation.getType());
    lastBitmapWidth = bitmap.getWidth();
    lastBitmapHeight = bitmap.getHeight();
  }
  blurScript.setRadius(blurRadius);
  blurScript.setInput(inAllocation);
  //do not use inAllocation in forEach. it will cause visual artifacts on blurred Bitmap
  blurScript.forEach(outAllocation);
  outAllocation.copyTo(bitmap);
  inAllocation.destroy();
  return bitmap;
