Magick::CoderInfo

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;
