/// The [`Image`][crate::Image] widget displays an image.
///
/// 
///
/// Various kinds of object can be displayed as an image; most typically,
/// you would load a [`gdk::Texture`][crate::gdk::Texture] from a file, using the convenience function
/// [`from_file()`][Self::from_file()], for instance:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkWidget *image = gtk_image_new_from_file ("myfile.png");
/// ```
///
/// If the file isn’t loaded successfully, the image will contain a
/// “broken image” icon similar to that used in many web browsers.
///
/// If you want to handle errors in loading the file yourself,
/// for example by displaying an error message, then load the image with
/// [`gdk::Texture::from_file()`][crate::gdk::Texture::from_file()], then create the [`Image`][crate::Image] with
/// [`from_paintable()`][Self::from_paintable()].
///
/// Sometimes an application will want to avoid depending on external data
/// files, such as image files. See the documentation of `GResource` inside
/// GIO, for details. In this case, [`resource`][struct@crate::Image#resource],
/// [`from_resource()`][Self::from_resource()], and [`set_resource()`][Self::set_resource()]
/// should be used.
///
/// [`Image`][crate::Image] displays its image as an icon, with a size that is determined
/// by the application. See [`Picture`][crate::Picture] if you want to show an image
/// at is actual size.

///
/// [`Image`][crate::Image] has a single CSS node with the name `image`. The style classes
/// `.normal-icons` or `.large-icons` may appear, depending on the
/// [`icon-size`][struct@crate::Image#icon-size] property.
