%  ThrowMagickException logs an exception as determined by the log
%  configuration file.  If an error occurs, MagickFalse is returned
%  otherwise MagickTrue.
%
%  The format of the ThrowMagickException method is:
%
%      MagickBooleanType ThrowFileException(ExceptionInfo *exception,
%        const char *module,const char *function,const size_t line,
%        const ExceptionType severity,const char *tag,const char *format,...)
%
%  A description of each parameter follows:
%
%    o exception: the exception info.
%
%    o filename: the source module filename.
%
%    o function: the function name.
%
%    o line: the line number of the source module.
%
%    o severity: Specifies the numeric error category.
%
%    o tag: the locale tag.
%
%    o format: the output format.
