<h3 align="center">Magick::CoderInfo</h3>
<p>The <i>CoderInfo</i> class provides the means to provide information regarding ImageMagick support for an image format (designated by a magick string). It may be used to provide support for a specific named format (provided as an argument to the constructor), or as an element of a container when format support is queried using the <a href="STL.html#coderInfoList">coderInfoList()</a> templated function.</p>
<p>The following code fragment illustrates how CoderInfo may be used.</p>
<p><tt><font color="#000066">CoderInfo info("GIF");</font></tt><br>
<tt><font color="#000066">cout << info->name() << ": (" << info->description() << ") : ";</font></tt><br>
<tt><font color="#000066">cout << "Readable = ";</font></tt><br>
<tt><font color="#000066">if ( info->isReadable() )</font></tt><br>
<tt><font color="#000066">cout << "true";</font></tt><br>
