Document resolution value given in dots per inch unit and it controls the dimensions of the empty page. Default value is 0 (use the current screen resolution).
The DocumentWriter class supports creating document with empty pages. To create an empty page, use a DocumentWriterPage structure with its EmfHandle set to IntPtr.Zero and pass it to the DocumentWriter.AddPage or DocumentWriter.InsertPage methods. You can control the size of this empty page in inches by setting the EmptyPageWidth, EmptyPageHeight and EmptyPageResolution properties to the desired values.
Note that in order to create empty pages, the PageRestriction property must be set to DocumentPageRestriction.Relaxed.
For an example, refer to DocumentWriter.
