See <a href="command-line-processing.html">Command Line Processing</a> for advice on how to structure your <code>magick</code> command or see below for example usages of the command.</p> 96 97<p>We list a few examples of the <code>magick</code> command here to illustrate its usefulness and ease of use. To get started, lets convert an image in the JPEG format to PNG:</p> 98 99<pre class="highlight"><code>magick rose.jpg rose.png 100</code></pre> 101 102<p>Next, we reduce the image size before it is written to the PNG format:</p> 103 104<pre class="highlight"><code>magick rose.jpg -resize 50% rose.png 105</code></pre> 106 107<ul> 108 <a href="../images/rose.jpg"> 109 <img src="../images/rose.jpg" width="70" height="46" alt="rose" /> 110 </a> 111 <img style="margin-top:13px; margin-bottom:13px;" src="../images/right.gif" width="20" height="20" alt="==>" /> 112 <a href="../images/rose.png"> 113 <img style="margin-top:11px; margin-bottom:12px;" src="../images/rose.png" width="35" height="23" alt="rose" /> 114 </a> 115</ul> 116 117<p>You can combine multiple image-processing operations to produce complex results:</p> 118 119<pre class="highlight"><code>magick -size 320x85 canvas:none -font Bookman-DemiItalic -pointsize 72 \ 120 -draw "text 25,60 \'Magick\'" -channel RGBA -blur 0x6 -fill darkred -stroke magenta \ 121 -draw "text 20,55 \'Magick\'" fuzzy-magick.png 122</code></pre> 123 124<ul> 125 <a href="../images/fuzzy-magick.png"><img src="../images/fuzzy-magick.png" width="320" height="85" alt="fuzzy-magick" /></a> 126</ul> 127 128<p>or here we resize an image with improved quality:</p> 129 130<pre class="highlight"><code>magick input.png -colorspace RGB +sigmoidal-contrast 11.6933 \ 131 -define filter:filter=Sinc -define filter:window=Jinc -define filter:lobes=3 \ 132 -resize 400% -sigmoidal-contrast 11.6933 -colorspace sRGB output.png'); 133</code></pre> 134 135<p>Utilize other command-line <a href="command-line-tools.html">tools</a> from the <code>magick</code> tool. To invoke this functionality, simply create a symbolic link to the <code>magick</code> tool or specify the tool you want to use as the first argument. These two methods are equivalent:</p> 136 137<pre class="highlight"><code>ln -s magick convert 138convert rose.jpg rose.png 139magick convert rose.jpg rose.png 140</code></pre> 141 142<p>You can find additional examples of using <code>magick</code> in <a href="https://legacy.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p> 143 144<h2><a class="anchor" id="options"></a>Option Summary</h2> 145 146<p>The <code>magick</code> command recognizes these options.
