public void DrawRectangle(
DXPen pen,
RectangleF bounds
)
Public Sub DrawRectangle(
pen As DXPen,
bounds As RectangleF
)
| Name | Type | Description |
|---|---|---|
| pen | DXPen |
A DXPen object that specifies the color, width, and style of the rectangle.
| | bounds | RectangleF |
A RectangleF structure that specifies a page area (in world coordinate system) where you can draw a rectangle.
|
Use this method to draw a rectangle in the page area specified by the bounds parameter.
To draw a shape on the PDF page, use one of the following methods:
PdfGraphics.AddToPageForeground, PdfGraphics.AddToPageBackgroundThese methods allow you to draw content on an existing page.PdfDocumentProcessor.RenderNewPageDraws content on a new page.
The following code snippet draws a rectangle in the specified area of the document page.
using DevExpress.Pdf;
using DevExpress.Drawing;
//...
using (PdfDocumentProcessor processor = new PdfDocumentProcessor()) {
processor.CreateEmptyDocument();
PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
using (PdfGraphics graphics = processor.CreateGraphicsPageSystem()) {
// Draw a rectangle.
using (var pen = new DXPen(Color.Red, 5))
graphics.DrawRectangle(pen, new RectangleF(50, 50, 500, 300));
// Add graphics content to the document page.
graphics.AddToPageForeground(page);
}
processor.SaveDocument("out2.pdf");
}
Process.Start("out.pdf");
Imports DevExpress.Pdf
Imports System.Drawing
'...
Using processor As New PdfDocumentProcessor()
processor.CreateEmptyDocument()
Dim page As PdfPage = processor.AddNewPage(PdfPaperSize.A4)
Using graphics As PdfGraphics = processor.CreateGraphicsPageSystem()
' Draw a rectangle.
Using pen As New DXPen(Color.Red, 5)
graphics.DrawRectangle(pen, New RectangleF(50, 50, 500, 300))
End Using
' Add graphics content to the document page.
graphics.AddToPageForeground(page)
End Using
processor.SaveDocument("out2.pdf")
End Using
Process.Start("out.pdf")
