    \brief The QPagedPaintDevice class represents a paint device that supports
    multiple pages.
 
    \ingroup painting
 
    Paged paint devices are used to generate output for printing or for formats like PDF.
    QPdfWriter and QPrinter inherit from it.

    \enum QPagedPaintDevice::PdfVersion
 
    The PdfVersion enum describes the version of the PDF file that
    is produced by QPrinter or QPdfWriter.
 
    \value PdfVersion_1_4 A PDF 1.4 compatible document is produced.
 
    \value PdfVersion_A1b A PDF/A-1b compatible document is produced.
 
    \value PdfVersion_1_6 A PDF 1.6 compatible document is produced.
           This value was added in Qt 5.12.
 
    \value [since 6.8] PdfVersion_X4 A PDF/X-4 compatible document is
           produced.
