%  WritePSImage translates an image to encapsulated Postscript
%  Level I for printing.  If the supplied geometry is null, the image is
%  centered on the Postscript page.  Otherwise, the image is positioned as
%  specified by the geometry.

%
%      MagickBooleanType WritePSImage(const ImageInfo *image_info,
%        Image *image,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%

%
%    o image: the image.
%
%    o exception: return any errors or warnings in this structure.
