    \class Q3PaintDeviceMetrics

    \brief The Q3PaintDeviceMetrics class provides information about a

    paint device.

    \compat

    Sometimes when drawing graphics it is necessary to obtain

    information about the physical characteristics of a paint device.

    This class provides the information. For example, to compute the

    aspect ratio of a paint device:

    \snippet doc/src/snippets/code/src_qt3support_painting_q3paintdevicemetrics.cpp 0

    Q3PaintDeviceMetrics contains methods to provide the width and

    height of a device in both pixels (width() and height()) and

    millimeters (widthMM() and heightMM()), the number of colors the

    device supports (numColors()), the number of bit planes (depth()),

    and the resolution of the device (logicalDpiX() and

    logicalDpiY()).

    It is not always possible for Q3PaintDeviceMetrics to compute the

    values you ask for, particularly for external devices. The

    ultimate example is asking for the resolution of of a QPrinter

    that is set to "print to file": who knows what printer that file

    will end up on?

*/

/*!

  \fn Q3PaintDeviceMetrics::Q3PaintDeviceMetrics(const QPaintDevice *pd)

    Constructs a metric for the paint device \a pd.

*/

/*!

    \fn int Q3PaintDeviceMetrics::width() const

    Returns the width of the paint device in default coordinate system

    units (e.g. pixels for QPixmap and QWidget).

*/

/*!

    \fn int Q3PaintDeviceMetrics::height() const

    Returns the height of the paint device in default coordinate

    system units (e.g. pixels for QPixmap and QWidget).

*/

/*!

    \fn int Q3PaintDeviceMetrics::widthMM() const

    Returns the width of the paint device, measured in millimeters.

*/

/*!

    \fn int Q3PaintDeviceMetrics::heightMM() const

    Returns the height of the paint device, measured in millimeters.

*/

/*!

    \fn int Q3PaintDeviceMetrics::numColors() const

    Returns the number of different colors available for the paint

    device. Since this value is an int will not be sufficient to represent

    the number of colors on 32 bit displays, in which case INT_MAX is

    returned instead.

*/

/*!

    \fn int Q3PaintDeviceMetrics::depth() const

    Returns the bit depth (number of bit planes) of the paint device.

*/

/*!

    \fn int Q3PaintDeviceMetrics::logicalDpiX() const

    Returns the horizontal resolution of the device in dots per inch,

    which is used when computing font sizes. For X, this is usually

    the same as could be computed from widthMM(), but it varies on

    Windows.

*/

/*!

    \fn int Q3PaintDeviceMetrics::logicalDpiY() const

    Returns the vertical resolution of the device in dots per inch,

    which is used when computing font sizes. For X, this is usually

    the same as could be computed from heightMM(), but it varies on

    Windows.
