<h1>ImageMagick Composite Command-line Tool</h1>
<p class="navigation-index">[<a href="#usage">Example Usage</a> &bull; <a href="#options">Option Summary</a>]</p>

<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>

<div style="margin: auto;">
  <h2><a id="usage"></a>Example Usage</h2>
</div>

<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>

<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>composite -gravity center smile.gif  rose: rose-over.png</span></p>
<div class="image">
<p>
  <a href="/images/smile.gif"><img src="/images/smile.gif" width="48" height="48" alt="smile" /></a>
  <img src="/images/over.gif" width="56" height="46" alt="over" />
  <a href="/images/rose.jpg"><img src="/images/rose.jpg" width="70" height="46" alt="rose" /></a>
  <img style="margin-top:13px; margin-bottom:13px;" src="/images/right.gif" width="20" height="20" alt="==>" />
  <a href="/images/rose-over.png"><img src="/images/rose-over.png" width="70" height="46" alt="rose" /></a>
</p>
</div>

<p>You can create three-dimensional effect with the <em>Atop</em>:</p>

<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert -size 70x70 xc:none -fill red -draw 'circle 35,35 10,30' red-circle.png</span><span class='crtout'></span><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert -size 70x70 xc:none -draw 'circle 35,35 35,20' -negate \ <br/>
  -channel A -gaussian-blur 0x8 white-highlight.png</span><span class='crtout'></span><span class="crtprompt"> $magick&gt; </span><span class='crtin'>composite -compose atop -geometry -13-17 white-highlight.png red-circle.png red-ball.png</span></p>

<div class="image">
<p>
  <a href="/images/white-highlight.png"><img src="/images/white-highlight.png" width="70" height="70" alt="white highlight" /></a>
  <img src="/images/atop.gif" width="56" height="70" alt="atop" />
  <a href="/images/red-circle.png"><img src="/images/red-circle.png" width="70" height="70" alt="red circle" /></a>
  <img style="margin-top:25px; margin-bottom:25px;" src="/images/right.gif" width="20" height="20" alt="==>" />
  <a href="/images/red-ball.png"><img src="/images/red-ball.png" width="70" height="70" alt="red ball" /></a>
</p>
</div>

<p>You can find additional examples of using <kbd>composite</kbd> in <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.  You can find out more about them and the mathematics by looking at <a href="http://www.w3.org/TR/SVG12/rendering.html">SVG Alpha Compositing</a></p>

<div style="margin: auto;">
  <h2><a id="options"></a>Option Summary</h2>
</div>

<p>The <kbd>composite</kbd> command recognizes these options.  Click on an option to get more details about how that option works.</p>
