<meta name="Description" content="ImageMagick (TM) is a free software suite to create, edit and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated. ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems. Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages Perl, C, C++, Python, PHP, Ruby or Java, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are available. This makes it possible to modify or create images automatically and dynamically. ImageMagick supports many image formats (over 90 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF."/>

<p>Use the <kbd>convert</kbd> program to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. See <a href="../www/command-line-processing.html">Command Line Processing</a> for advice on how to structure your <kbd>convert</kbd> command or see below for example usages of the command.</p>
<div style="margin: auto;">
<h2><a name="usage"></a>Example Usage</h2>
</div>
<p>We list a few examples of the <kbd>convert</kbd> command here to illustrate its usefulness and ease of use. To get started, lets convert an image in the JPEG format to PNG:</p>
<pre class="text">
convert rose.jpg rose.png
</pre>
<p>Next, we reduce the image size before it is written to the PNG format:</p>
<pre class="text">
convert rose.jpg -resize 50% rose.png
</pre>
<p class="image">
<a href="../images/rose.jpg"><img src="../images/rose.jpg" width="70" height="46" align="middle" alt="rose" /></a>
<img src="../images/right.gif" width="20" height="20" align="middle" alt="==>" />
<a href="../images/rose.png"><img src="../images/rose.png" width="35" height="23" align="middle" alt="rose" /></a>
</p>
<p>You can combine multiple image-processing operations to produce complex results:</p>
<pre class="text">
convert -size 320x85 xc:transparent -font Bookman-DemiItalic -pointsize 72 -draw "text 25,60 'Magick'" \
-channel RGBA -gaussian 0x6 -fill darkred -stroke magenta -draw "text 20,55 'Magick'" fuzzy-magick.png
</pre>
<p class="image">
<a href="../images/fuzzy-magick.png"><img src="../images/fuzzy-magick.png" width="320" height="85" align="middle" alt="fuzzy-magick" /></a>
</p>
<p>You can find additional examples of using <kbd>convert</kbd> in <a href="http://www-106.ibm.com/developerworks/library/l-graf/?ca=dnt-428" target="429597281">Graphics from the Command Line</a>. Further discussion is available in <a href="http://www-106.ibm.com/developerworks/library/l-graf2/?ca=dgr-lnxw15GraphicsLine" target="1730660630">More Graphics from the Command Line</a> and <a href="http://www.cit.gu.edu.au/~anthony/graphics/imagick6" target="1833845333">Examples of ImageMagick Usage</a>.</p>
