%% DISABLE HYPERLINKS AND BOOKMARKS
%% -----------------------------------------------------------------------------
%
% Files for PDF/X cannot have hyperlinks. If your document has any,
% they will be functionally disabled. However, it is still necessary
% to ensure that you do not specify them in the wrong color space.
% Since `novel' class disallows any kind of color, `xcolor' is loaded with
% `monochrome' or `gray' option, prior to loading `hyperref'.
%
% Your text will be K black, rather than CMYK `rich black'. This is best.
% If you use a grayscale image anywhere, ask your print service whether it may
% be directly placed as grayscale (and they will convert to halftone)
% or whether you must convert it to halftone yourself, and place it that way.
%
% Note that LaTeX cannot detect any erroneous placement of a color image.
%
% The pagegrid package can only be used in draft mode, without PDF/X:
\gdef\@reallyOFF{off}
\@ifpackageloaded{pagegrid}{
  \if@useDraftMode\else
    \ClassError{novel}{\string\pagegrid\space needs `draft' mode^^J}%
     {\string\pagegrid\space may only be used with class option `draft'^^J}%
  \fi
  \ifpdfx@isOFF\else
    \pdfx@isOFFtrue % cancels pdfx when using pagegrid (in draft mode)
    \gdef\@reallyOFF{re-set to off by pagegrid package.}
    \ClassWarning{novel}{You requested PDF/X compliance.^^J%
     But you also used the \string\pagegrid\space package. Cannot have both.^^J%
     So instead, your document was processed with \string\SetPDFX\space off.^^J%
     Reason: The grid and text are in layers. No layers allowed.^^J}%

%% PREPARE PDF /INFO METADATA
%% -----------------------------------------------------------------------------
%% PDF /Info is another form of metadata, older than XMP but still used.
%% It is NOT in utf-8 encoding. Depending on content, one of two encodings
%%   will be automatically used: PDFDoc encoding if metadata uses only
%%   characters within Latin-1, or utf-16 if metadata is not within Latin-1.
%% Either way, the input was utf-8 before processing.
%% In principle, PDF /Info is obsolete whenever PDF/X is used, because
%%   XMP metadata is supposed to prevail through the printing workflow.
%% In practice, things don't always work that way. So, unless your PDF
%%   has no metadata, essential items are re-encoded and copied to PDF /Info.
%% Other than encoding, XMP metadata and PDF /Info must be exactly the same.
%% All of those issues are handled automatically here.
%% The result is written at the end of the PDF, after the document.
%
