| ## 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; instead it allows to create Cairo |
| drawing contexts which can be used to draw on [class@Gdk.Surface]s. |
| |
| 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/). |
