Properties:

• public Surface Internal { construct; get; }
  The internal Cairo.Surface backing the surface.
• public int Width { construct; get; }
  The width of the surface.
• public int Height { construct; get; }
  The height of the surface.
• public Context Context { construct; get; }
  A Cairo.Context for the surface.

Creation methods:

• public Surface (int width, int height)
  Creates a new surface.
• public Surface.with_cairo_surface (int width, int height, Surface model)
  Creates a new surface compatible with an existing Cairo.Surface.
• public Surface.with_surface (int width, int height, Surface model)
  Creates a new surface compatible with an existing Surface.
• public Surface.with_internal (ImageSurface image)
  Creates a new surface with the given Cairo.ImageSurface as Internal.

Methods:

• public void clear ()
  Clears the entire surface.
• public Surface copy ()
  Create a copy of the surface
• public Surface scaled_copy (int width, int height)
  Create a scaled copy of the surface
• public Pixbuf to_pixbuf ()
  Saves the current surface to a Gdk.Pixbuf.
• public Surface create_mask (double threshold, out Rectangle extent)
  Computes the mask of the surface.
• public Color average_color ()
  Computes and returns the average color of the surface.
• public void fast_blur (int radius, int process_count = 1)
  Performs a fast blur on the surface.
• public void exponential_blur (int radius)
  Performs an exponential blur on the surface.
• public void gaussian_blur (int radius)
  Performs a gaussian blur on the surface. Note: This method is wickedly slow
