public double UserSpaceResolution {get; set;}
Typically, a PDF page's default user space resolution is 72 DPI. Beginning with PDF 1.6, some pages may specify user space resolutions other than 72 DPI. This is accomplished with an optional page dictionary key, UserUnit, that specifies the size of default user space units in multiples of 1/72 inches. When this key is missing or does not specify a positive value, the default value of 1.0 is assumed.
Applications that report physical dimensions, such as inches or centimeters, should read this property to accurately convert user space units into lengths.
Note: Modifying this property value does not change the source PDF page's user space resolution.
