       Gtk2::Ex::FormFactory::Image - An Image in a FormFactory framework


         Gtk2::Ex::FormFactory::Image->new (
           bgcolor       => Background color of the widget,
           with_frame    => Draw a frame around the image?,
           scale_to_fit  => Automatially scale the image in its container?,
           max_width     => Maximum width the image may scale to,
           max_height    => Maximum height the image may scale to,
           scale         => Display the image with this constant scaling,
           scale_hook    => Callback which returns the actual scale,
           Gtk2::Ex::FormFactory::Widget attributes


       This class implements an Image in a Gtk2::Ex::FormFactory framework.  The image is always
       displayed with its natural aspect ratio, but there are various possibilities to control
       the scaling of the image.

       The value of the associated application object attribute is the filename of the displayed
       image. The file format must be supported by Gtk2::Gdk::PixBuf.



         +--- Gtk2::Ex::FormFactory::Image



       Attributes are handled through the common get_ATTR(), set_ATTR() style accessors, but they
       are mostly passed once to the object constructor and must not be altered after the
       associated FormFactory was built.

       bgcolor = "RGB Hex Triple" [optional]
           This is the background color of the widget. If set all areas of the widget not filled
           with the image are painted with this color.

       with_frame = BOOL [optional]
           If set to TRUE a frame is rendered around the image.

       scale_to_fit = BOOL [optional]
           If set to TRUE the image will automatically scale proportionally into to the space the
           container of this widget allocated for the image widget.

       max_width = INTEGER [optional]
           With this attribute you can define a maximm width the image may scale to.

       max_height = INTEGER [optional]
           With this attribute you can define a maximm height the image may scale to.

       scale = FLOAT [optional]
           If you set this attribute, no dynamic scaling applies, but the image will be
           constantly scaled with this value. This overrides all other attributes regarding
           dynamic scaling.

       scale_hook = CODEREF(FormFactory::Image, PixBuf) [optional]
           This code reference is called if the image needs an update e.g. if the associated
           application object attribute changed or the parent was resized and scale_to_fit was

           The Gtk2::Ex::FormFactory::Image instance and the Gtk2::Gdk::PixBuf of the image are
           passed to the function.

           If scale_to_fit is set the widget's dimension are tracked automatically. The actual
           width and height are stored in the attributes widget_width and widget_height and thus
           can be accessed from the callback by calling get_widget_width and get_widget_width.

       For more attributes refer to Gtk2::Ex::FormFactory::Widget.
