PdfDocumentProcessor.RenderNewPage(PdfRectangle, PdfGraphics) Method

Adds a new page with specified page size and created graphics to a document.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v18.2.dll

Declaration

C#

public int RenderNewPage(
    PdfRectangle mediaBox,
    PdfGraphics graphics
)

VB.NET

Public Function RenderNewPage(
    mediaBox As PdfRectangle,
    graphics As PdfGraphics
) As Integer

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.

Returns

Type	Description
Int32	An integer value, specifying the page number. The page number is started from 1.

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 graphics content represented by the PdfGraphics object to a PDF document.

Example

The PDF Document Processor allows you to draw graphic primitives on the PDF page, such as lines, Bezier curves, polygons, ellipses, paths, an image and a string.

This example shows how to draw a business card in the document foreground. To accomplish this task, do the following:

• Create a PDF document processor and add an empty document to it by calling the PdfDocumentProcessor.CreateEmptyDocument method.
• Create PDF graphics represented by an instance of the PdfGraphics class by calling the PdfDocumentProcessor.CreateGraphics method. To access PdfGraphics, you need to reference the DevExpress.Pdf.Drawing assembly.
• To draw an image on the PDF page, call the PdfGraphics.DrawImage method for the specified image at the specified location with the specified size.
• To draw text, call the PdfGraphics.DrawString method at the specified location with the specified Brush and Font objects.
• Render a page with created graphics by calling the PdfDocumentProcessor.RenderNewPage method.
