Properties inherited from ILDisplay
BOOL	KeepAspectRatio [get, set]
	Whether the display control should keep the aspect ratio when zooming.
int	PixelUnderMouse [get]
	The pixel value under current cursor's position.
Properties inherited from ILDisplayCommon
LPVAlignment	Alignment [get, set]
	The alignment the control is used when fit some part of the scene to the window.
BOOL	AutoRefreshEnabled [get, set]
	Enables or disables automatically display re-rendering triggered by add/remove objects or regions or the image. By default, it's on.
OLE_COLOR	BackColor [get, set]
	The background color of the display control.
LPVDisplayFlags	DisplayFlags [get, set]
	The display flags, see LPVDisplayFlags.
BOOL	DrawingEnabled [get, set]
	Enables or disables all display rendering. Useful when performing many graphics or image operations at once.
LPVScrollBarPolicy	HScrollBarPolicy [get, set]
	The policy of the horizontal scroll bar, see LPVScrollBarPolicy.
double	PanX [get, set]
	The scene's translation in the x-coordinate direction for panning. The final display x position is calculated as: \( (x + panX) \times zoomX \).
double	PanY [get, set]
	The scene's translation in the y-coordinate direction for panning. The final display y position is calculated as: \( (y + panY) \times zoomY \).
LPVScrollBarPolicy	VScrollBarPolicy [get, set]
	The policy of the vertical scroll bar, see LPVScrollBarPolicy.
double	Zoom [set]
	Set the scene's zoom factor in both x- and y-coordinate direction.
LPVZoomAnchor	ZoomAnchor [get, set]
	How the control should position the scene when resized, see LPVZoomAnchor.
double	ZoomX [get, set]
	The scene's zoom factor in or out in the x-coordinate direction.
double	ZoomY [get, set]
	The scene's zoom factor in or out in the y-coordinate direction.
