	CleanupInstance	Performs finalization on long strings, variants, and interface variables within a class.
	CopyRect	Copies part of an image from another canvas into the canvas.
	Create	Creates an instance of TMetafileCanvas and acquires a handle to a metafile device context.
	CreateWithComment	Creates an instance of TMetafileCanvas and acquires a handle to a metafile device context with a comment string.
	DefaultHandler	Provides the interface for a method that processes message records.
	Destroy	Destroys an instance of the TMetafileCanvas after transferring the image to the TMetafile object that was passed to the constructor.

	Ellipse	This is the overview for the Ellipse method overload.
	FieldAddress	Returns the address of a published object field.
	FillRect	Fills the specified rectangle on the canvas using the current brush.
	FloodFill	Fills an area of the canvas using the current brush.
	FrameRect	Draws a rectangle using the Brush of the canvas to draw the border.
	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.
	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.
	HandleAllocated	Indicates whether the TCanvas object has acquired a handle to a device context.
	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.
	LineTo	Draws a line on the canvas from PenPos to the point specified by X and Y, and sets the pen position to (X, Y).
	Lock	Prevents other threads from drawing on the canvas.
	MethodAddress	This is MethodAddress, a member of class TObject.
	MethodName	This is MethodName, a member of class TObject.
	MoveTo	Changes the current drawing position to the point (X,Y).
	NewInstance	Allocates memory for an instance of an object type and returns a pointer to that new instance.
	Pie	Draws a pie-shaped the section of the ellipse bounded by the rectangle (X1, Y1) and (X2, Y2) on the canvas.
	PolyBezier	Draws a set of Bezier curves.
	PolyBezierTo	Draws a set of Bezier curves and updates the value of PenPos.
	Polygon	Draws a series of lines on the canvas connecting the points passed in and closing the shape by drawing a line from the last point to the first point.
	Polyline	Draws a series of lines on the canvas with the current pen, connecting each of the points passed to it in Points.
	Rectangle	This is the overview for the Rectangle method overload.
	Refresh	Deselects the Pen, Brush, and Font from the device context.
	RoundRect	Draws a rectangle with rounded corners on the canvas.
	SafeCallException	Handles exceptions in methods declared using the safecall calling convention.
	StretchDraw	Draws the graphic specified by the Graphic parameter in the rectangle specified by the Rect parameter.
	TextExtent	Returns the width and height, in pixels, of a string rendered in the current font.
	TextHeight	Returns the height, in pixels, of a string rendered in the current font.
	TextOut	Writes a string on the canvas, starting at the point (X,Y), and then updates the PenPos to the end of the string.
	TextRect	This is the overview for the TextRect method overload.
	TextWidth	Returns the width, in pixels, of a string rendered in the current font.
	TryLock	Locks the canvas if it is currently unlocked.
	Unlock	Decreases the LockCount property, allowing other threads to execute when LockCount reaches 0.
