Calculate Page Setup Scaling Factor

When you set Page Setup Scaling using Fit to n page(s) wide by m tall option, Microsoft Excel calculates the Page Setup Scaling Factor. You can calculate the same thing using SheetRender.page_scale property. This property returns a double value, which can be converted to a percentage. For example, if it returns 0.5, then it means the scaling factor is 50%.

The following sample code illustrates how to calculate the Page Setup scaling factor using the SheetRender.page_scale property.
