<p>The CoderInfo class supports obtaining information about
GraphicsMagick 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 coderInfoList()
templated function.</p>
<p>The following code fragment illustrates how CoderInfo may be used:</p>
<pre class="literal-block">
CoderInfo info(&quot;GIF&quot;);
cout &lt;&lt; info-&gt;name() &lt;&lt; &quot;: (&quot; &lt;&lt; info-&gt;description() &lt;&lt; &quot;) : &quot;;
cout &lt;&lt; &quot;Readable = &quot;;
if ( info-&gt;isReadable() )
  cout &lt;&lt; &quot;true&quot;;
else
  cout &lt;&lt; &quot;false&quot;;
cout &lt;&lt; &quot;, &quot;;
cout &lt;&lt; &quot;Writable = &quot;;
if ( info-&gt;isWritable() )
  cout &lt;&lt; &quot;true&quot;;
else
  cout &lt;&lt; &quot;false&quot;;
cout &lt;&lt; &quot;, &quot;;
cout &lt;&lt; &quot;Multiframe = &quot;;
if ( info-&gt;isMultiframe() )
  cout &lt;&lt; &quot;true&quot;;
else
  cout &lt;&lt; &quot;false&quot;;
cout &lt;&lt; endl;
</pre>
<p>The definition of class 'Magick::CoderInfo' is:</p>
<pre class="literal-block">
namespace Magick
{
  class MagickDLLDecl CoderInfo
  {
  public:

    enum MatchType {
      AnyMatch,       // match any coder
      TrueMatch,      // match coder if true
      FalseMatch      // match coder if false
    };

    // Default constructor
    CoderInfo ( void );

    // Copy constructor
    CoderInfo ( const CoderInfo &amp;coder_ );

    // Construct with coder name
    CoderInfo ( const std::string &amp;name_ );

    // Destructor
    ~CoderInfo ( void );

    // Format name
    std::string name( void ) const;

    // Format description
    std::string description( void ) const;

    // Format is readable
    bool isReadable( void ) const;

    // Format is writeable
    bool isWritable( void ) const;

    // Format supports multiple frames
    bool isMultiFrame( void ) const;

    // Assignment operator
    CoderInfo&amp; operator= (const CoderInfo &amp;coder_ );

  };
}
