Remarks

The coordinate system for the ZoomToRect method has its origin at the top-left corner of the Visio Viewer window. Positive directions are to the right (x) and down (y). The units of measurement are pixels.

The ZoomToRect method, in effect, crops a rectangular section of the drawing, specified by the parameters, and then displays that section in the entire Visio Viewer window. The parameters are a set of two pairs of coordinates, the first pair specifying the upper-left corner of the section, and the second pair the lower-right corner.

Example

The following code zooms to display a rectangular section of the drawing that is open in Visio Viewer. The upper-left corner of the displayed section corresponds to the upper-left corner of the Visio Viewer window as originally displayed. The lower-right corner corresponds to a point 300 pixels down and 300 pixels to the right of the upper-left corner in that original display.
