Shaping an image like a circle

A circular shape can add a stylish touch to portrait photographs, an organizational chart, or photos on a website.

How to do it...

As in the previous recipe, we will define a TikZ macro for this purpose. Take a look at the following steps:

1. Load the TikZ package:

   \usepackage{tikz}

2. Define a macro so we can use it often:

   \newcommand{\roundpic}[4][]{
     \tikz\node [circle, minimum width = #2,
       path picture = {
         \node[#1] at (path picture bounding box.center){
           \includegraphics[width=#3]{#4}};
       }] {};}

3. Use the new macro within your document to include an image:

   \roundpic[xshift=-1cm,
     yshift=-2.6cm]{5.8cm}{9cm}{filename}

4. Compile the document. When I used a photo of my dog (here using xshift and yshift to select the desired area of the photo), I got the following image:
