	ClassParent	Returns the type of the immediate ancestor of a class.
	ClassType	Returns the class reference for the object's class.
	CleanupInstance	Performs finalization on long strings, variants, and interface variables within a class.
	Compress	Forces the action of compression.
	Create	Instantiates a jpeg image object.
	DefaultHandler	Provides the interface for a method that processes message records.
	Destroy	Destroys an instance of a jpeg image object.
	DIBNeeded	Decompress the jpeg image into a bitmap.
	Dispatch	Calls message-handling methods for the object, based on the contents of the Message parameter.
	FieldAddress	This is the overview for the FieldAddress method overload.
	Free	Destroys an object and frees its associated memory, if necessary.
	FreeInstance	Deallocates memory allocated by a previous call to the System::TObject::NewInstance method.
	GetHashCode	Returns an integer containing the hash code.
	GetInterface	Retrieves a specified interface.
	GetInterfaceEntry	Returns the entry for a specific interface implemented in a class.
	GetInterfaceTable	Returns a pointer to a structure containing all of the interfaces implemented by a given class.
	GetNamePath	Returns the name of the object as it appears in the Object Inspector.
	InheritsFrom	Determines the relationship of two object types.
	InitInstance	Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
	InstanceSize	Returns the size in bytes of each instance of the object type.
	JPEGNeeded	Creates a new TJPEGData object if the jpeg image only has a bitmap and a jpeg is needed.
	LoadFromClipboardFormat	Reads in a jpeg image from the Clipboard into the jpeg image object.
	LoadFromFile	Loads a graphic image stored in a file.

	MethodAddress	This is the overview for the MethodAddress method overload.
	MethodName	Returns the name of a class method by address.
	NewInstance	Allocates memory for an instance of an object type and returns a pointer to that new instance.
	QueryInterface	Returns a reference to a specified interface if the object supports that interface.
	QueryInterface	Returns a reference to a specified interface if the object supports that interface.
	SafeCallException	Handles exceptions in methods declared using the safecall calling convention.
	SaveToClipboardFormat	Writes a jpeg image to a variable in Clipboard format.
	SaveToFile	Saves a graphics image to a file.
