Document resolution value given in dots per inch unit and it controls the dimensions of the resulting document. Default value is 0 (use the resolution of the actual page).
When creating documents, the DocumentWriter object will use the resolution set in the Enhanced Metafile handle passed to DocumentWriter.AddPage or DocumentWriter.InsertPage methods through DocumentWriterEmfPage.EmfHandle. However, sometimes it is desirable to override this behavior and use a pre-calculated fixed value for the resolution instead. To do this, change the value of the DocumentResolution property from the default value of 0 to the desired value before any calls to DocumentWriter.AddPage or DocumentWriter.InsertPage.
For an example, refer to DocumentWriter.
