The previous recipe gave us an edged image. It can be nice to have rounded corners, so let us take a look at how to achieve that.

1. Load the tikz package in your preamble:

   \usepackage{tikz}

2. Declare a box for storing the image:

   \newsavebox{\picbox}

3. Define a macro that allows us to use our recipe repeatedly:

   \newcommand{\cutpic}[3]{

         \node at (path picture bounding box.center) {
           \usebox{\picbox}};
       }] {};}

4. Use the new macro within your document to include ...
