    int pageNumber
)

VB.NET

Public Sub AddLinkToPage(
    linkArea As RectangleF,
    pageNumber As Integer
)

Example

This example shows how to create a document with graphics and add a hyperlink to a page and URI. To accomplish this task:

• Create an empty document with no pages by calling one of the PdfDocumentProcessor.CreateEmptyDocument overloaded methods.
• 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.
• Draw the graphic content (e.g., an image, a string, lines, polygons) by calling the corresponding Draw method.
• Add a link to the page and to a URI using the PdfGraphics.AddLinkToPage and PdfGraphics.AddLinkToUri methods.
• Render a page with created graphics by calling the PdfDocumentProcessor.RenderNewPage method.
