Gtk.Image
Description: Reference for Gtk.Image

### Class

# GtkImage

#### Description [src]

    final class Gtk.Image : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

The `GtkImage` widget displays an image.

Various kinds of object can be displayed as an image; most typically, you would load a `GdkTexture` from a file, using the convenience function `gtk_image_new_from_file()`, for instance:

    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_new_from_file()`, then create the `GtkImage` with `gtk_image_new_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, `GtkImage:resource`, `gtk_image_new_from_resource()`, and `gtk_image_set_from_resource()` should be used.

`GtkImage` displays its image as an icon, with a size that is determined by the application. See `GtkPicture` if you want to show an image at is actual size.

## CSS nodes

`GtkImage` has a single CSS node with the name `image`. The style classes `.normal-icons` or `.large-icons` may appear, depending on the `GtkImage:icon-size` property.

## Accessibility

`GtkImage` uses the `GTK_ACCESSIBLE_ROLE_IMG` role.
