Public Methods

	Name	Description

	AfterConstruction	Responds after the last constructor has executed.
	Assign	Copies a new bitmap image to the bitmap object.
	BeforeDestruction	Responds before the first destructor executes.
	ClassInfo	Returns a pointer to the runtime type information (RTTI) table for the object type.
	ClassName	Returns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument).

	Destroy	Disposes of the instance of the bitmap object.
	Dispatch	Calls message-handling methods for the object, based on the contents of the Message parameter.
	Dormant	Creates a memory bitmap image in order to release the bitmap handle, forcing the image into DIB format to save resources.
	FieldAddress	Returns the address of a published object field.

	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.
	HandleAllocated	Indicates whether the TBitmap object has acquired a handle to the underlying GDI object.
	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.
	LoadFromClipboardFormat	Loads a bitmap from the Clipboard into the bitmap object.
	LoadFromFile	Loads a graphic image stored in a file.
	LoadFromResourceID	Loads a bitmap from a resource into the bitmap object.
	LoadFromResourceName	Loads a bitmap resource into the bitmap object.
	LoadFromStream	Loads the bitmap from a stream into the bitmap object.
	Mask	Converts the current bitmap image into a monochrome mask, replacing TransparentColor with white and every other color with black.
	MethodAddress	This is MethodAddress, a member of class TObject.
	MethodName	This is MethodName, a member of class TObject.
	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.
	ReleaseHandle	Returns the handle to the bitmap so that the TBitmap object no longer knows about the handle.
	ReleaseMaskHandle	Returns the handle to the bitmap's mask so that the TBitmap object no longer knows about the mask handle.
	ReleasePalette	Returns the handle to the bitmap's palette and disassociates the palette from the TBitmap object.
	SafeCallException	Handles exceptions in methods declared using the safecall calling convention.
	SaveToClipboardFormat	Creates a local copy of the bitmap in Clipboard format.
	SaveToFile	Saves a graphics image to a file.
