Public Member Functions

 gradient (int mode, image *L)
 Compute the magnitude of the gradient of image L. This is the value of the greatest rate of change in that image. This behaves as an omni- directional edge detect. Mode gives the wrap mode.
 
virtual double get (int i, int j, int k) const
 Return the value of the sample at row i, column j, channel k.
 
virtual void doc (std::ostream &out) const
 Produce a string documenting the function of this object.
 
- Public Member Functions inherited from image
 image (image *L=0, image *R=0)
 Create a new image object with left child L and right child R. The parents of L and R are set to this.
 
virtual ~image ()
 Finalize this image object by deleting any children.
 
virtual int get_height () const
 Return the height of this image.
 
virtual int get_width () const
 Return the height of this image.
 
virtual int get_depth () const
 Return the depth of this image.
 
imagegetL ()
 Return the left child.
 
imagegetR ()
 Return the right child.
 
imagegetP ()
 Return the parent.
 
virtual void tweak (int a, int v)
 Tweak image parameter a, changing the value by a factor of v.
 
virtual void process ()
 Process all samples of both children.
