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 \sa {How to Create Qt Plugins} */ /*! \fn bool QPictureFormatPlugin::installIOHandler(const QString &format) Installs a QPictureIO picture I/O handler for the picture format \a format. \sa keys() */ /*!
