PdfGraphics.DrawImage(Image, RectangleF, RectangleF, GraphicsUnit) Method

Draws the specified image part in a page rectangle.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v24.1.Drawing.dll

NuGet Package: DevExpress.Pdf.Drawing


public void DrawImage(
    Image image,
    RectangleF destRect,
    RectangleF srcRect,
    GraphicsUnit srcUnit


Name Type Description
image Image

An image to draw.

destRect RectangleF

A page rectangle in world coordinate system where you can draw an image. The image portion is scaled to fit the rectangle.

srcRect RectangleF

A portion of the image to draw.

srcUnit GraphicsUnit

Indicates the measurement units used by the srcRect parameter.


This method renders an image with its original resolution (DPI). The following formats are available:

  • BMP
  • JPEG
  • PNG
  • EMF
  • EMF+
  • TIFF
  • GIF
  • SVG

The method’s dpiX and dpiY parameters do not affect image quality. They are used to convert world coordinates to page coordinates only.

If you embed a multi-page TIFF image into the document, the PdfGraphics instance draws the active frame only (the default active frame is the first frame). Use the Image.SelectActiveFrame method to select a frame to use. The compression retains for TIFF images with CCITT T.4 or CCITT T.6 compression.

You can use the following properties to reduce the image size and the size of the resulting PDF:

  • ConvertImagesToJpeg - Specifies whether to convert bitmap images into JPEG to reduce the size of the resulting PDF file.
  • JpegImageQuality - Gets or sets the quality of JPEG images in the resulting PDF file.


The PdfDocumentProcessor caches image data used as the DrawImage method parameter. If you need to draw the same image on multiple pages, you can reuse image data to improve the application performance and reduce the resulting file size.

To draw an image on the PDF page, use one of the following methods:

PdfGraphics.AddToPageForeground, PdfGraphics.AddToPageBackground
These methods allow you to draw content on an existing page.
Draws content on a new page.

The code sample below shows how to draw a portion of an image in the specified page region. When the this part of the image is bigger than the specified region, the image is scaled to fit the region:

image at the center

using DevExpress.Pdf;
using System.Drawing;

using (var processor = new PdfDocumentProcessor())

    using (PdfGraphics graphics = processor.CreateGraphics())
        // Obtain the first document page
        PdfPage page = processor.Document.Pages[0];

        // Specify an image to draw
        using (Image image = Image.FromFile("Documents//DevExpress.png"))
          // Define an image part to draw:
          RectangleF imageRect = new RectangleF(0,0, 200,200);

          // Define an image position
          RectangleF pageRect = new RectangleF(106, 363, 100, 100);

          // Draw an image into the calculated area
          graphics.DrawImage(image, pageRect,imageRect,GraphicsUnit.Pixel);

          // Add graphics content to the page foreground
          graphics.AddToPageForeground(page, 72, 72);
