|
|
<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>
|
|
<pre class="code">
|
|
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";
|

cout << "false";
