    \class QPageSize
    \inmodule QtGui
    \since 5.3
    \brief The QPageSize class describes the size and name of a defined page size.

    This class implements support for the set of standard page sizes as defined
    in the Adobe Postscript PPD Standard v4.3. It defines the standard set of
    page sizes in points, millimeters and inches and ensures these sizes are
    consistently used. Other size units can be used but will be calculated
    results and so may not always be consistent. The defined point sizes are
    always a integer, all other sizes can be fractions of a unit.

    The defined size is always in width x height order with no implied page
    orientation. Note that it is possible for page sizes to be defined where the
    width is greater than the height, such as QPageSize::Ledger, so you cannot
    rely on comparing the width and height values to determine page orientation.

    For example, A4 is defined by the standard as 210mm x 297mm, 8.27in x 11.69in,
    or 595pt x 842pt.

    You can also define custom page sizes with custom names in any units you want
    and this unit size will be preserved and used as the base for all other unit
    size calculations.

    When creating a QPageSize using a custom QSize you can choose if you want
    QPageSize to try match the size to a standard page size. By default
    QPaperSize uses a FuzzyMatch mode where it will match a given page size to
    a standard page size if it falls within 3 postscript points of a defined
    standard size. You can override this to request only an exact match but this
    is not recommended as conversions between units can easily lose 3 points and
    result in incorrect page sizes.

    A QPageSize instance may also be obtained by querying the supported page sizes
    for a print device. In this case the localized name returned is that defined
    by the printer itself. Note that the print device may not support the current
    default locale language.

    The class also provides convenience methods for converting page size IDs to and from
    various unit sizes.
