Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
The Zoom object is a member of the Zooms collection.
Use Zooms(index), where index identifies the view type, to return a single Zoom object. The view type specified by index can be one of the following WdViewType constants: wdMasterView, wdNormalView, wdOutlineView, wdPrintPreview, wdPrintView, or wdWebView.
The Add method isn't available for the Zooms collection. The Zooms collection includes a single Zoom object for each of the various view types (outline, normal, page layout, and so on).
