174<p>Use the <kbd>composite</kbd> program to overlap one image over another. See <a href="../www/command-line-processing.html">Command Line Processing</a> for advice on how to structure your <kbd>composite</kbd> command or see below for example usages of the command.</p>

180<p>We list a few examples of the <kbd>composite</kbd> command here to illustrate its usefulness and ease of use. To get started, lets overlay a smiley face over a rose:</p>
