\section{Magick::CoderInfo}
\scriptsize{
\begin{verbatim}
The CoderInfo 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 coderInfoList() templated function.
The following code fragment illustrates how CoderInfo may be used.
CoderInfo info("GIF");
cout << info->name() << ": (" << info->description() << ") : ";
cout << "Readable = ";
if ( info->isReadable() )
cout << "true";
else
cout << "false";
cout << ", ";
cout << "Writable = ";
if ( info->isWritable() )
cout << "true";
else
cout << "false";
cout << ", ";
cout << "Multiframe = ";
if ( info->isMultiframe() )
cout << "true";
else
cout << "false";
cout << endl;
The methods available in the CoderInfo class are shown in the following
table:
CoderInfo Methods
