Inheritance diagram for swizzle:

Public Member Functions
	swizzle (std::string element, image *L)
	Reorder, replicate, or remove channels of L. Element is a string of digits used as channel indices. The height and width of the output match those of the input, but the depth of the output equals the length of the element string. More...
virtual double	get (int i, int j, int k) const
	Return the value of the sample at row i, column j, channel k.
virtual int	get_depth () const
	Return the depth of this image.
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.
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.
virtual void	process ()
	Process all samples of both children.

Additional Inherited Members
Protected Attributes inherited from image
image *	L

image *	P
	Parent.

Constructor & Destructor Documentation

swizzle::swizzle ( std::string  element, image *  L  )

inline

For example 210 would produce a BGR output from an RGB input. 1 would isolate the green channel. 000 would route the red channel to all three channels. 0121 would duplicate the green channel as an alpha channel.

Elements indices are base 36, which allows inputs of up to 36 channels: 0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.
