PdfDocumentProcessor.CreateBitmap(Int32, Int32) Method

Exports a PDF page to a bitmap image.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v23.2.dll

NuGet Package: DevExpress.Document.Processor


public Bitmap CreateBitmap(
    int pageNumber,
    int largestEdgeLength


Name Type Description
pageNumber Int32

A page number.

largestEdgeLength Int32

A length of the image’s largest dimension, in pixels.


Type Description

The converted page.


The largestEdgeLength parameter determines the output image height for pages in the portrait orientation and width – for landscape pages. The page is proportionally scaled so that the largest edge of the converted bitmap is equal to the largestEdgeLength value.

You can reduce the output image size and memory consumption if you pass a smaller largestEdgeLength value to the CreateBitmap method.


The CreateBitmap method uses GDI/GDI+ rendering and works only on Windows OS. The PlatformNotSupportedException is thrown on other operating systems. Use the CreateDXBitmap method in non-Windows environments.


The following example illustrates how to convert pages to bitmap images.

View Example

using DevExpress.Pdf;
using System.Drawing;

static void Main(string[] args)

  int largestEdgeLength = 1000;

  using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
      // Load a document.

      for (int i = 1; i <= processor.Document.Pages.Count; i++)
          // Export pages to bitmaps.
          Bitmap image = processor.CreateBitmap(i, largestEdgeLength);

          // Save the bitmaps.
          image.Save("..\\..\\MyBitmap" + i + ".bmp");
