Public Member Functions
virtual void	getRangeAB (float &lowA, float &highA, float &lowB, float &highB)=0
	Get the input range for this color space. The range of the L component is always implicitly 0 to 100.
virtual void	getWhitePoint (float &x, float &y, float &z)=0
	Get the White Point in CIE 1931 XYZ space.
virtual void	getBlackPoint (float &x, float &y, float &z)=0
	Get the Black Point in CIE 1931 XYZ space.
Public Member Functions inherited from IDOMColorSpace
virtual eColorSpaceType	getColorSpaceType ()=0
	Retrieves the color space type.
virtual uint8	getNumComponents ()=0
	Retrieves the number of components that are in colors in this color space.
virtual bool	getComponentsHaveSameRange ()=0
	Checks if this color space has the same range for all its components. Some color spaces (such as Lab and ICC) may not have the same range for all its components. If a color space does have the same range for all its components, you only need to call getComponentRange() once to find the range for all components.
virtual bool	getComponentRange (int component, float &low, float &high)=0
	Retrieves the expected range of component values for a given channel, if applicable.
virtual eRenderingIntent	getDefaultRenderingIntent ()=0
	Retrieves the default rendering intent for this color space.
virtual EDLRawString	getColorantName (uint8 component) const =0
	Determine the colorant name for a colorant index. If a colorant name cannot be determined, an IEDLError with type EDL_ERR_NO_COLOR_NAME will be thrown. Cannot be called on Indexed or LAB color spaces. For device spaces and simple ICC color spaces, the basic process color name will be returned (ie one of Gray, Red, Green, Blue, Cyan, Magenta, Yellow, Black as appropriate).
virtual bool	equals (const IDOMColorSpacePtr &colorSpace, bool exact=false)=0
	Determines if the given color space is equivalent to this color space.
virtual bool	similar (const IDOMColorSpacePtr &colorSpace, eRenderingIntent intent, eBlackPointCompensation bpc)=0
	Determines if the given color space is very similar to this color space for the given rendering intent. Color spaces are tested via selective sampling and are considered similar if the samples show the same results to a 10 bit accuracy. This can be an expensive operation for complicated color spaces.
Public Member Functions inherited from IEDLObject
virtual const CClassID &	getClassID () const =0
	Returns class ID of IEDLObject.
virtual bool	init (CClassParams *pData)
	The init() method is called to perform any post-construction initialization of an IEDLObject that has been created by the EDL class factory, before it is actually returned by the factory.
virtual bool	clone (IEDLObjectPtr &ptrObject, IEDLClassFactory *pFactory)
	Create a copy of EDLObject.
Public Member Functions inherited from IRCObject
virtual void	addRef () const =0
	Increases the reference count of the actual object pointed to. This would take place during an assignment or copying.
virtual bool	decRef () const =0
	Decreases the reference count of the actual object pointed to. When the reference count falls to Zero, it deletes the actual object pointed to.
virtual int32	getRefCount () const =0
	Retrieve the current reference count of the actual object pointed to.
Public Member Functions inherited from IDOMHashable
virtual	~IDOMHashable ()
	Virtual destructor.
virtual bool	hash (uint64 &hash)=0
	Retrieve a hash for this object.
virtual uint64	hashE ()
	As hash(), but throws an exception if the operation fails.

	Retrieves class id of IDOMColorSpaceLAB.
