Comments
All of the above properties except Specification are requests to the PDF viewer (although they are stored in the PDF document). Different viewers may or may not obey all of the requested options. In particular, some viewers may override the PageLayout, FitWindow, and/or CenterWindow options depending on how the viewer was previously configured or opened.
Caution
The PDFX directives are quite persnikety (that's the technical term) about formating. Be careful to write the commands exactly as shown here, make sure commas are commas and periods are periods. PDFX does NOT generate error messages, so you won't know that a command has failed unless you test for the expected condition.
Examples for PDFX5
//PDFX,General.MagnificationType,FitPage
//; scale the document to fit one page into the window (instruction to viewer)
//PDFX,General.OpenToPage,1
//; request opening to 2nd page (starting at 0)
//PDFX,General.Specification,5
//; direct that the PDF be produced using PDF version 1.5 specification
//PDFX,General.Specification,-3
//; direct that the PDF be produced using PDF/A (archive) specification, version 1a
Examples for PDFX3
//PDFX,General.PDFSpec,5
//; direct that the PDF be produced using PDF version 1.5 specification
//PDFX,General.FitWindow,1
//; tell PDF viewer to display document as big as possible within window
Compatibility
PDFXv3 supports only specifications 1.3 thru 1.6 and does not support PDF/A (Specification = negative number). Several of the above properties are new in PDFXv5, or have changed names. PDFXv3 names will be up-converted to be compatible with PDFXv5+ as needed, but not vice versa.
