How to scale a large bitmap to a squared bitmap

After I take a photo I want to view it in a square. I follow this guide, but the bitmap created is rectangular, it creates a scaled image. My question is: what should I change in that code to create a scaled squared image?

I don't think it's possible to do this using BitmapFactory.Options.

A simple way to do it (this creates another bitmap so will use up memory) is:

    Bitmap output;
    if (bitmap.getWidth() >= bitmap.getHeight())
        output = Bitmap.createBitmap(bitmap, bitmap.getWidth() / 2 - bitmap.getHeight() / 2, 0, bitmap.getHeight(), bitmap.getHeight());
    else
        output = Bitmap.createBitmap(bitmap, 0, bitmap.getHeight() / 2 - bitmap.getWidth() / 2, bitmap.getWidth(), bitmap.getWidth());
