Viewer.ZoomToPoint method (Visio Viewer)

Resizes the drawing that is open in Microsoft Visio Viewer to the specified percentage of its previous size, and places the upper-left corner of the drawing at the specified point in the Visio Viewer window, measured in pixels in the coordinate system of the window.

Syntax

expression.ZoomToPoint (X, Y, Percentage)

expression An expression that returns a Viewer object.

Parameters

Name	Required/Optional	Data type	Description
X	Required	Long	The x-coordinate, in pixels in the coordinate system of the Visio Viewer window, of the point to place the upper-left corner of the drawing.
Y	Required	Long	The y-coordinate, in pixels in the coordinate system of the Visio Viewer window, of the point to place the upper-left corner of the drawing.
Percentage	Required	Double	The percentage of zoom.

Return value

Nothing

Remarks

Setting the Percentage parameter to 1 displays the drawing at its original size. Setting it to 2 doubles the length on both sides of the drawing by that factor, thus quadrupling the size of the drawing. Setting it to 0.5 displays the page at one-quarter its original size.

The origin of the coordinate system of the Visio Viewer window is its upper-left corner. The positive x-direction is to the right, and the positive y-direction is down.

Example

The following code displays the drawing at half its previous size, and places the upper-left corner of the drawing at a point 200 pixels to the right and 200 pixels below the upper-left corner of the Visio Viewer window.

vsoViewer.ZoomToPoint 200, 200, 0.5
