#Returns
Type | Description |

Int32 | An integer value, specifying the page number. |
#Remarks
The overloaded RenderNewPage method automatically converts world coordinates to page coordinates. See Coordinate Systems to learn more.
Use this method to add a new page with the specified DPI and the graphics content represented by the PdfGraphics object to a PDF document.
To render graphics on a PDF document page, pass 72 as a DPI value to this method. The DPI value you pass into this method does not affect graphics quality and used for coordinates transformation only (world coordinates to page coordinates). For example, the 72 DPI value allows you to transform coordinates without any scaling.
