Declaration

public int RenderNewPage(
    PdfRectangle mediaBox,
    PdfGraphics graphics,
    float dpiX,
    float dpiY
)

Parameters

Name Type Description
mediaBox PdfRectangle

A PdfRectangle object that is the page size, in points (1/72 of an inch).

graphics PdfGraphics

A PdfGraphics object that contains all graphics content that allows an application to draw on the page.

dpiX Single

A Single object that represents the value, in dots per inch, for the horizontal resolution.

dpiY Single

A Single object that represents the value, in dots per inch, for the vertical resolution.

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, 72 DPI value allows transforming coordinates without any scaling.
