-    Defines a picture I/O handler for the picture format called \a
-    format, which is recognized using the regular
-    expression defined in \a header, read using \a readPicture and
-    written using \a writePicture.
-
-    \a flags is a string of single-character flags for this format.
-    The only flag defined currently is T (upper case), so the only
-    legal value for \a flags are "T" and the empty string. The "T"
-    flag means that the picture file is a text file, and Qt should treat
-    all newline conventions as equivalent. (XPM files and some PPM
-    files are text files for example.)
-
-    \a format is used to select a handler to write a QPicture; \a header
-    is used to select a handler to read an picture file.
-
-    If \a readPicture is \nullptr, the QPictureIO will not be able
-    to read pictures in \a format. If \a writePicture is \nullptr,
-    the QPictureIO will not be able to write pictures in \a format. If
-    both are null, the QPictureIO object is valid but useless.
-
-    Example:
-    \snippet picture/picture.cpp 6
-    \codeline
-    \snippet picture/picture.cpp 7
-    \codeline
-    \snippet picture/picture.cpp 8
-
-    Before the regular expression test, all the 0 bytes in the file header are
-    converted to 1 bytes. This is done because when Qt was ASCII-based, QRegExp
-    could not handle 0 bytes in strings.
-
-    The regexp is only applied on the first 14 bytes of the file.
-
-    (Note that if one handlerIO supports writing a format and another
-    supports reading it, Qt supports both reading and writing. If two
-    handlers support the same operation, Qt chooses one arbitrarily.)

-    \class QPictureFormatPlugin
-    \brief The QPictureFormatPlugin class provides an abstract base
-    for custom picture format plugins.
-
-    \ingroup plugins
-    \inmodule QtGui
-
-    The picture format plugin is a simple plugin interface that makes
-    it easy to create custom picture formats that can be used
-    transparently by applications.
-
-    Writing an picture format plugin is achieved by subclassing this
-    base class, reimplementing the pure virtual functions
-    loadPicture(), savePicture(), and installIOHandler(), and
-    exporting the class with the Q_PLUGIN_METADATA() macro.
-
-    The json file containing the metadata should contain one entry
-    with the list of picture formats supported by the plugin:
-
-    \code
-    { "Keys": [ "mypictureformat" ] }
-    \endcode
