PDFViewCtrlSetZoom Method (Int32, Int32, Double)

Sets the zoom factor to a new value using the given pixel coordinate (x,y) as a zoom center, which will stay fixed on the screen. The zoom point (x,y) is represented in the screen coordinate system, which starts in the upper-left corner of the client window. Should you want to move (x, y) to the center of the client window, you can use the OnScroll() subsequently:

public bool SetZoom(
	int x,
	int y,
	double zoom
)

Public Function SetZoom ( 
	x As Integer,
	y As Integer,
	zoom As Double
) As Boolean

public:
virtual bool SetZoom(
	[InAttribute] int x, 
	[InAttribute] int y, 
	[InAttribute] double zoom
) sealed

function SetZoom(x, y, zoom);
