| ## Functions to support using cairo |
| |
| [Cairo](http://cairographics.org) is a graphics library that supports vector |
| graphics and image compositing that can be used with GTK. |
| |
| GDK does not wrap the Cairo API and it is not possible to use cairo directly |
| to draw on a [class@Gdk.Surface]. You can either use a |
| [GtkDrawingArea](../gtk4/class.DrawingArea.html) widget or |
| [gtk_snapshot_append_cairo](../gtk4/func.Snapshot.append_cairo.html) |
| for drawing with cairo in a GTK4 application. |
| |
| Additional functions allow use [struct@Gdk.Rectangle]s with Cairo |
| and to use [struct@Gdk.RGBA], `GdkPixbuf`, and [class@Gdk.Surface] |
| instances as sources for drawing operations. |
| |
| For more information on Cairo, please see the |
| [Cairo API reference](https://www.cairographics.org/manual/). |
