| ZoomIndex | BYTE |
The ZoomIndex property contains a value indicating which zoom factor is applied. The PrintPreviewClass object uses this property to identify and apply the selected zoom factor. The SetZoomPercentile method sets the ZoomIndex property.
Implementation:
The ZoomIndex value “points” to one of the 7 standard zoom settings or to a user zoom setting. The PrintPreviewClass object sets the ZoomIndex value when the end user selects a zoom setting from one of the zoom menus or from the zoom combo box. The standard zoom choices are defined in ABREPORT.TRN as follows:
| No Zoom | Displays the specified number of pages (PagesAcross and PagesDown properties) in a tiled arrangement in the preview window. |
| Page Width | Displays a single page whose width is the same as the width of the preview window. |
| 50% | Displays a single page at 50% of actual print size. |
| 75% | Displays a single page at 75% of actual print size. |
| 100% | Displays a single page at 100% of actual print size. |
| 200% | Displays a single page at 200% of actual print size. |
| 300% | Displays a single page at 300% of actual print size. |
A ZoomIndex value of zero (0) indicates a nonstandard zoom factor is specified. Nonstandard zoom factors may be specified when the AllowUserZoom property is True. The UserPercentile property contains the nonstandard zoom factor.
