The CogOCFont type exposes the following members.

Constructors

	Name	Description
	CogOCFont	Constructs a new instance of this class.
	CogOCFont(IntPtr)	Constructs a new instance of this class using com pointer.
	CogOCFont(CogOCFont)	Constructs a new instance of this class as a deep copy of the given instance.

Methods

	Name	Description
	Clone	Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject
	Compile	Compiles this font which involves computing the confusion scores for all possible model pairings in the font.
	Confusable	Returns true if the specified model pair are confusable. Two models are confusable if their Confusion score is greater than the ConfusionThreshold specified by the user.
	Confusion	Get the Confusion score for the specified model pair. The Confusion score for a pair of models is the probability, on a scale of 0 to 1, that the two models will be confused with each other during verification.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose
	Dispose(Boolean)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	ExportToCvlArchive	Exports this font to the specified CVL archive as a ccOCAlphabetPtrh. If this font is compiled then the CVL will contain a compiled font.
	Finalize	(Overrides Object Finalize .)
	GetAttributes	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetClassName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetComponentName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetConverter	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultEvent	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultProperty	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEditor	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetObjectData
	GetProperties	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetProperties( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetPropertyOwner	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ImportFromCvlArchive	Imports a ccOCAlphabet class from the specified CVL archive file into this CogOCFont class. The archive should contain a single ccOCAlphabet. Import will try to load from the CVL archive via either a ccOCAlphabet or a ccOCAlphabetPtrh.
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	ResumeAndRaiseChangedEvent	Re-enables raising of the Changed event after SuspendChangedEvent has been called. Also raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent.
	SuspendChangedEvent	Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
	Uncompile	Uncompile this font.

Fields

	Name	Description
	SfCompiled	This bit will be set in the EventArgs of a Changed event every time the value returned by Compiled may have changed.
	SfConfusable	This bit will be set in the EventArgs of a Changed event every time the value returned by Confusable may have changed.
	SfConfusion	This bit will be set in the EventArgs of a Changed event every time the value returned by Confusion may have changed.
	SfConfusionThreshold	This bit will be set in the EventArgs of a Changed event every time the value returned by ConfusionThreshold may have changed.
	SfDescription	This bit will be set in the EventArgs of a Changed event every time the value returned by Description may have changed.
	SfFontModels	This bit will be set in the EventArgs of a Changed event every time the value returned by FontModels may have changed.
	SfTimeout	This bit will be set in the EventArgs of a Changed event every time the value returned by Timeout may have changed.
	SfTimeoutEnabled	This bit will be set in the EventArgs of a Changed event every time the value returned by TimeoutEnabled may have changed.

Properties

	Name	Description
	ChangedEventSuspended	If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called.
	Compiled	True if the font is compiled.
	ConfusionThreshold	Threshold at which two models are considered Confusable. A compiled font contains Confusion scores for all model pairs in the font. A score greater than this threshold indicates that a model pair should be considered confusing.
	Description	Description simply provides a string for the user to store additional information or comments about their font.
	FontModels	Collection of font models for this font.
	HasChanged	If true, the serializable state of this object has changed since the last time it was serialized.
	Timeout	The maximum time (msec) allowed to compile the font. If compilation has not finished by the end of the timeout period, it will stop soon thereafter and return E_Cog_TimeoutExpired. This value only applies if TimeoutEnabled is true.
	TimeoutEnabled	If true then the Timeout property limits the amount of time allowed for compilation of the font. If false then timeout is disabled and the Timeout property is ignored.

Events

	Name	Description
	Changed	Occurs when one or more parts of the object's state may have changed.

Remarks

Interface for an optical character font. This interface includes properties and methods that let you specify the font's confusion threshold, determine how confusable font model pairs are, and Compile the font. It also contains the collection of models that make up the font.
