<P>The <I>CoderInfo</I> class provides the means to provide
information regarding 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 <A HREF="STL.html#coderInfoList">coderInfoList()</A>
templated function.
</P>
<P>The following code fragment illustrates how CoderInfo may be used.
