Image file writer.

Inheritance diagram for output:

Public Member Functions
	output (std::string name, char type, image *L)
	Write a raw-formatted data file named name. Type is a character giving the output sample type. The image height, width, and depth are given by the L image object. Unsigned samples are clamped to the range [0,1] and signed samples to the range [-1,+1] before being cast to the destination data type.
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.
virtual void	process ()
	Process all samples of this image, storing them in the file. Then, switch into cached mode, sourcing all subsequent sampling from the file instead of invoking the process. This is useful as an optimization, especially for processes that feed large-kernel convolutions, as it eliminates the need to repeatedly compute expensive samples.
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.
image *	getL ()
	Return the left child.
image *	getR ()
	Return the right child.
image *	getP ()
	Return the parent.
virtual void	tweak (int a, int v)
	Tweak image parameter a, changing the value by a factor of v.

Additional Inherited Members
