+ * @Title: Pixbufs
+ *
+ * Pixbufs are client-side images. For details on how to create
+ * and manipulate pixbufs, see the #GdkPixbuf API documentation.
+ *
+ * The functions described here allow to obtain pixbufs from
+ * #GdkWindows and cairo surfaces.

+/**
+ * gdk_pixbuf_get_from_window:
+ * @window: Source window
+ * @src_x: Source X coordinate within @window
+ * @src_y: Source Y coordinate within @window
+ * @width: Width in pixels of region to get
+ * @height: Height in pixels of region to get
+ *
+ * Transfers image data from a #GdkWindow and converts it to an RGB(A)
+ * representation inside a #GdkPixbuf. In other words, copies
+ * image data from a server-side drawable to a client-side RGB(A) buffer.
+ * This allows you to efficiently read individual pixels on the client side.
+ *
+ * This function will create an RGB pixbuf with 8 bits per channel with
+ * the same size specified by the @width and @height arguments. The pixbuf
+ * will contain an alpha channel if the @window contains one.
+ *
+ * If the window is off the screen, then there is no image data in the
+ * obscured/offscreen regions to be placed in the pixbuf. The contents of
+ * portions of the pixbuf corresponding to the offscreen region are undefined.
+ *
+ * If the window you're obtaining data from is partially obscured by
+ * other windows, then the contents of the pixbuf areas corresponding
+ * to the obscured regions are undefined.
+ *
+ * If the window is not mapped (typically because it's iconified/minimized
+ * or not on the current workspace), then %NULL will be returned.
+ *
+ * If memory can't be allocated for the return value, %NULL will be returned
+ * instead.
+ *
+ * (In short, there are several ways this function can fail, and if it fails
+ * it returns %NULL; so check the return value.)
+ *
+ * Return value: (transfer full): A newly-created pixbuf with a reference
+ * count of 1, or %NULL on error

+ * gdk_pixbuf_get_from_surface:
+ * @surface: surface to copy from
+ * @src_x: Source X coordinate within @surface
+ * @src_y: Source Y coordinate within @surface
+ * @width: Width in pixels of region to get
+ * @height: Height in pixels of region to get
+ *
+ * Transfers image data from a #cairo_surface_t and converts it to an RGB(A)
+ * representation inside a #GdkPixbuf. This allows you to efficiently read
+ * individual pixels from cairo surfaces. For #GdkWindows, use
+ * gdk_pixbuf_get_from_window() instead.
+ *
+ * This function will create an RGB pixbuf with 8 bits per channel.
+ * The pixbuf will contain an alpha channel if the @surface contains one.
+ *
+ * Return value: (transfer full): A newly-created pixbuf with a reference
+ * count of 1, or %NULL on error
