+    \brief Qt SVG provides functionality for handling SVG images.
+
+    Scalable Vector Graphics (SVG) is an XML-based language for
+    describing two-dimensional vector graphics. Qt provides classes
+    for rendering and displaying SVG drawings in widgets and on other
+    paint devices.
+
+    \section1 Getting Started
+
+    Qt SVG provides classes for rendering SVG files. To include the definitions
+    of the module's classes, use the following directive:
+
+    \snippet doc_src_qtsvg.cpp 0
+
+    To link against the module, add this line to your \l qmake \c
+    .pro file:
+
+    \snippet doc_src_qtsvg.pro 1
+
+    \section1 Licenses and Attributions
+
+    Qt SVG is available under commercial licenses from \l{The Qt Company}.
+    In addition, it is available under the
+    \l{GNU Lesser General Public License, version 3}, or
+    the \l{GNU General Public License, version 2}.
+    See \l{Qt Licensing} for further details.
+
+    Furthermore Qt SVG contains third party
+    code under following permissive licenses:
+
+    \generatelist{groupsbymodule attributions-qtsvg}
+
+    \section1 Articles
+    \list

+    \brief Rendering SVG files with the Qt SVG module
+
+    Qt SVG provides classes for rendering SVG files. To include the definitions
+    of the module's classes, use the following directive:
+
+    \snippet doc_src_qtsvg.cpp 0
+
+    To link against the module, add this line to your \l qmake \c
+    .pro file:
+
+    \snippet doc_src_qtsvg.pro 1
+
+    \section1 Rendering SVG Files
+
+    Scalable Vector Graphics (SVG) is a language for describing two-dimensional
+    graphics and graphical applications in XML. SVG 1.1 is a W3C Recommendation
+    and forms the core of the current SVG developments in Qt. SVG 1.2 is the
+    specification currently being developed by the \l{SVG Working Group}, and it
+    is \l{http://www.w3.org/TR/SVG12/}{available in draft form}. The \l{Mobile
+    SVG Profiles} (SVG Basic and SVG Tiny) are aimed at resource-limited devices
+    and are part of the 3GPP platform for third generation mobile phones. You
+    can read more about SVG at \l{About SVG}.
+
+    Qt supports the \l{SVG 1.2 Tiny Static Features}{static features} of
+    \l{http://www.w3.org/TR/SVGMobile12}{SVG 1.2 Tiny}. ECMA scripts and DOM manipulation are currently not
+    supported.
+
+    SVG drawings can be rendered onto any QPaintDevice subclass. This
+    approach gives developers the flexibility to experiment, in order
+    to find the best solution for each application.
+
+    The easiest way to render SVG files is to construct a QSvgWidget and
+    load an SVG file using one of the QSvgWidget::load() functions.
+
+    QSvgRenderer is the class responsible for rendering SVG files for
+    QSvgWidget, and it can be used directly to provide SVG support for
+    custom widgets.
+    To load an SVG file, construct a QSvgRenderer with a file name or the
+    contents of a file, or call QSvgRenderer::load() on an existing
+    renderer. If the SVG file has been loaded successfully the
+    QSvgRenderer::isValid() will return true.
+
+    Once you have loaded the SVG file successfully, you can render it
+    with the QSvgRenderer::render() function. Note that this scheme allows
+    you to render SVG files on all paint devices supported by Qt, including
+    QWidget, QGLWidget, and QImage. See the \l{SVG Viewer Example}{SVG Viewer}
+    example for more details.

+    \class QGraphicsSvgItem
+    \inmodule QtSvg
+    \ingroup graphicsview-api
+    \brief The QGraphicsSvgItem class is a QGraphicsItem that can be used to render
+           the contents of SVG files.
+
+    \since 4.2
+
+    QGraphicsSvgItem provides a way of rendering SVG files onto QGraphicsView.
+    QGraphicsSvgItem can be created by passing the SVG file to be rendered to
+    its constructor or by explicit setting a shared QSvgRenderer on it.
+
+    Note that setting QSvgRenderer on a QGraphicsSvgItem doesn't make the item take
+    ownership of the renderer, therefore if using setSharedRenderer() method one has
+    to make sure that the lifetime of the QSvgRenderer object will be at least as long
+    as that of the QGraphicsSvgItem.
+
+    QGraphicsSvgItem provides a way of rendering only parts of the SVG files via
+    the setElementId. If setElementId() method is called, only the SVG element
+    (and its children) with the passed id will be renderer. This provides a convenient
+    way of selectively rendering large SVG files that contain a number of discrete
+    elements. For example the following code renders only jokers from a SVG file
+    containing a whole card deck:
+
+    \snippet src_svg_qgraphicssvgitem.cpp 0
+
+    Size of the item can be set via direct manipulation of the items
+    transformation matrix.
+
+    By default the SVG rendering is cached using QGraphicsItem::DeviceCoordinateCache
+    mode to speedup the display of items. Caching can be disabled by passing
+    QGraphicsItem::NoCache to the QGraphicsItem::setCacheMode() method.

+    \class QSvgRenderer
+    \inmodule QtSvg
+    \ingroup painting
+
+    \brief The QSvgRenderer class is used to draw the contents of SVG files onto paint devices.
+    \since 4.1
+    \reentrant
+
+    Using QSvgRenderer, Scalable Vector Graphics (SVG) can be rendered onto any QPaintDevice
+    subclass, including QWidget, QImage, and QGLWidget.
+
+    QSvgRenderer provides an API that supports basic features of SVG rendering, such as loading
+    and rendering of static drawings, and more interactive features like animation. Since the
+    rendering is performed using QPainter, SVG drawings can be rendered on any subclass of
+    QPaintDevice.
+
+    SVG drawings are either loaded when an QSvgRenderer is constructed, or loaded later
+    using the load() functions. Data is either supplied directly as serialized XML, or
+    indirectly using a file name. If a valid file has been loaded, either when the renderer
+    is constructed or at some later time, isValid() returns true; otherwise it returns false.
+    QSvgRenderer provides the render() slot to render the current document, or the current
+    frame of an animated document, using a given painter.
+
+    The defaultSize() function provides information about the amount of space that is required
+    to render the currently loaded SVG file. This is useful for paint devices, such as QWidget,
+    that often need to supply a size hint to their parent layout.
+    The default size of a drawing may differ from its visible area, found using the \l viewBox
+    property.
+
+    Animated SVG drawings are supported, and can be controlled with a simple collection of
+    functions and properties:
+
+    \list
+    \li The animated() function indicates whether a drawing contains animation information.
+    \omit
+    \li The animationDuration() function provides the duration in milliseconds of the
+       animation, without taking any looping into account.
+    \li The \l currentFrame property contains the current frame of the animation.
+    \endomit
+    \li The \l framesPerSecond property contains the rate at which the animation plays.
+    \endlist
+
+    Finally, the QSvgRenderer class provides the repaintNeeded() signal which is emitted
+    whenever the rendering of the document needs to be updated.

+    \class QSvgWidget
+    \inmodule QtSvg
+    \ingroup painting
+
+    \brief The QSvgWidget class provides a widget that is used to display the contents of
+    Scalable Vector Graphics (SVG) files.
+    \since 4.1
+
+    This class enables developers to display SVG drawings alongside standard widgets, and
+    is used in much the same way as QLabel is used for displaying text and bitmap images.
+
+    Since QSvgWidget is a subclass of QWidget, SVG drawings are rendered using the properties
+    of the display. More control can be exercised over the rendering process with the
+    QSvgRenderer class, as this can be used to paint onto other paint devices, such as QImage
+    and QGLWidget. The renderer used by the widget can be obtained with the renderer()
+    function.
+
+    Each QSvgWidget can be constructed with the file name of a SVG file, or they can be
+    constructed without a specific file to render and one can be supplied later. The load()
+    functions provide two different ways to load an SVG file: they accept either the file name
+    of an SVG file or a QByteArray containing the serialized XML representation of an SVG file.
+
+    By default, the widget provides a size hint to reflect the size of the drawing that it
+    displays. If no data has been loaded, the widget provides the default QWidget size hint.
+    Subclass this class and reimplement sizeHint() if you need to customize this behavior.
