/**
 * gdk_pixbuf_new_from_data:
 * @data: Image data in 8-bit/sample packed format.
 * @format: Color format used for the data.
 * @has_alpha: Whether the data has an opacity channel.
 * @width: Width of the image in pixels.
 * @height: Height of the image in pixels.
 * @rowstride: Distance in bytes between rows.
 * @dfunc: Function used to free the data when the pixbuf's reference count
 * drops to zero, or NULL if the data should not be freed.
 * @dfunc_data: Closure data to pass to the destroy notification function.
 * 
 * Creates a new #GdkPixbuf out of in-memory RGB data.
 * 
 * Return value: A newly-created #GdkPixbuf structure with a reference count of
 * 1.
