+%
+%  InvokePostscriptDelegate() executes the Postscript interpreter with the
+%  specified command.
+%
+%  The format of the InvokePostscriptDelegate method is:
+%
+%      MagickBooleanType InvokePostscriptDelegate(
+%        const MagickBooleanType verbose,const char *command,
+%        ExceptionInfo *exception)
+%
+%  A description of each parameter follows:
+%
+%    o verbose: A value other than zero displays the command prior to
+%      executing it.
+%
+%    o command: the address of a character string containing the command to
+%      execute.
+%
+%    o exception: return any errors or warnings in this structure.
