| <p class="text-center"><a href="composite.php#usage">Example Usage</a> • <a href="composite.php#options">Option Summary</a></p> |
| |
| <p class="lead magick-description">Use the <code>composite</code> program to overlap one image over another. See <a href="command-line-processing.php">Command Line Processing</a> for advice on how to structure your <code>composite</code> command or see below for example usages of the command.</p> |
| |
| <h2 class="magick-header"><a id="usage"></a>Example Usage</h2> |
| |
| <p>We list a few examples of the <code>composite</code> command here to illustrate its usefulness and ease of use. To get started, lets overlay a smiley face over a rose:</p> |
| |
| <pre> |
| composite -gravity center smile.gif rose: rose-over.png |
| </pre> |
| |
| <ul> |
| <a href="../image/smile.gif"><img src="../image/smile.gif" width="48" height="48" alt="smile" /></a> |
| <img src="../image/over.gif" width="56" height="46" alt="over" /> |
| <a href="../image/rose.jpg"><img src="../image/rose.jpg" width="70" height="46" alt="rose" /></a> |
| <img style="margin-top:13px; margin-bottom:13px;" src="../image/right.gif" width="20" height="20" alt="==>" /> |
| <a href="../image/rose-over.png"><img src="../image/rose-over.png" width="70" height="46" alt="rose" /></a> |
| </ul> |
| |
| <p>You can create three-dimensional effect with the <var>Atop</var>:</p> |
| |
| <pre> |
| convert -size 70x70 canvas:none -fill red -draw 'circle 35,35 10,30' red-circle.png |
| convert -size 70x70 canvas:none -draw 'circle 35,35 35,20' -negate \ |
| -channel A -gaussian-blur 0x8 white-highlight.png |
| composite -compose atop -geometry -13-17 white-highlight.png red-circle.png red-ball.png |
| </pre> |
| |
| <ul> |
| <a href="../image/white-highlight.png"><img src="../image/white-highlight.png" width="70" height="70" alt="white highlight" /></a> |
| <img src="../image/atop.gif" width="56" height="70" alt="atop" /> |
| <a href="../image/red-circle.png"><img src="../image/red-circle.png" width="70" height="70" alt="red circle" /></a> |
| <img style="margin-top:25px; margin-bottom:25px;" src="../image/right.gif" width="20" height="20" alt="==>" /> |
| <a href="../image/red-ball.png"><img src="../image/red-ball.png" width="70" height="70" alt="red ball" /></a> |
| </ul> |
| |
| <p>You can find additional examples of using <code>composite</code> 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> |
| |
| <h2 class="magick-header"><a id="options"></a>Option Summary</h2> |
| |
| <p>The <code>composite</code> command recognizes these options. Click on an option to get more details about how that option works.</p> |
