# DockSurface

## Object Hierarchy:

## Description:

public class DockSurface : Object

A dock surface is a wrapper class for a Cairo.Surface. It encapsulates a surface/context and provides utility methods.

Namespace: Plank.Drawing
Package: plank

## Content:

### Properties:

- public Surface Internal { construct; get; }
  The internal Cairo.Surface backing the dock 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 dock surface.

### Creation methods:

- public DockSurface (int width, int height)
  Creates a new dock surface.
- public DockSurface.with_surface (int width, int height, Surface model)
  Creates a new dock surface compatible with an existing Cairo.Surface.
- public DockSurface.with_dock_surface (int width, int height, DockSurface model)
  Creates a new dock surface compatible with an existing Drawing.DockSurface.
- public DockSurface.with_internal (ImageSurface image)
  Creates a new dock surface with the given Cairo.ImageSurface as Internal.

### Methods:

- public void clear ()
  Clears the entire surface.
- public DockSurface copy ()
  Create a copy of the surface
- public DockSurface scaled_copy (int width, int height)
  Create a scaled copy of the surface
- public Pixbuf to_pixbuf ()
  Saves the current dock surface to a Gdk.Pixbuf .
- public DockSurface 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
