The new PDF Document API lets you export PDF pages as images. You can export one or more pages to Bitmap or SVG format.

Call the PdfDocument.ExportToImages method and pass an array of page indexes to export the corresponding pages to images.

The following code snippet exports the first, third, and fifth pages of a PDF document to BMP images:

C#

using DevExpress.Docs.Pdf;
using DevExpress.Drawing;

using (PdfDocument pdfDocument =
    new PdfDocument(File.OpenRead(@"document_001.pdf")))
{
    var images = pdfDocument.ExportToImages(new int[] { 1, 3, 5 });

    for (int i = 0; i < images.Length; i++)
    {
        using (var stream = new FileStream(String.Format("document_001_page_{0}.bmp", i + 1), FileMode.Create))
        {
            images[i].Save(stream, DXImageFormat.Bmp);
        }
    }
}

VB.NET

Imports DevExpress.Docs.Pdf
Imports DevExpress.Drawing

Using pdfDocument As New PdfDocument(File.OpenRead("document_001.pdf"))
    Dim images = pdfDocument.ExportToImages(New Integer() {1, 3, 5})

    For i As Integer = 0 To images.Length - 1
        Using stream As New FileStream(String.Format("document_001_page_{0}.bmp", i + 1), FileMode.Create)
            images(i).Save(stream, DXImageFormat.Bmp)
        End Using
    Next
End Using

The ImageExportOptions class allows you to specify the image format, resolution, and other export options. Pass the ImageExportOptions object as the PdfDocument.ExportToImages method parameter to apply these options.

The following code snippet exports the first, third, and fifth pages of a PDF document to BMP images at 300 DPI and with a maximum edge length of 1000 pixels.

C#

using DevExpress.Docs.Pdf;
using DevExpress.Drawing;

using (PdfDocument pdfDocument =
    new PdfDocument(File.OpenRead(@"document_001.pdf")))

{
    ImageExportOptions exportOptions = new ImageExportOptions();
    exportOptions.ImageExportType = ImageExportType.Bitmap;
    exportOptions.Resolution = 300;
    exportOptions.LargestEdgeLength = 1000;

    var images = pdfDocument.ExportToImages(exportOptions, new int[] { 1, 3, 5 });

    for (int i = 0; i < images.Length; i++)
    {
        using (var stream = new FileStream(String.Format("document_001_page_{0}.bmp", i + 1), FileMode.Create))
        {
            images[i].Save(stream, DXImageFormat.Bmp);
        }
    }
}

VB.NET

Imports DevExpress.Docs.Pdf
Imports DevExpress.Drawing

Using pdfDocument As New PdfDocument(File.OpenRead("document_001.pdf"))
    Dim exportOptions As New ImageExportOptions()
    exportOptions.ImageExportType = ImageExportType.Bitmap
    exportOptions.Resolution = 300
    exportOptions.LargestEdgeLength = 1000

    Dim images = pdfDocument.ExportToImages(exportOptions, New Integer() {1, 3, 5})

    For i As Integer = 0 To images.Length - 1
        Using stream As New FileStream(String.Format("document_001_page_{0}.bmp", i + 1), FileMode.Create)
            images(i).Save(stream, DXImageFormat.Bmp)
        End Using
    Next
End Using
