VB.NET
'Initialize the PdfViewer Control
Dim pdfViewer As PdfViewerControl = New PdfViewerControl()
'Load the input PDF file
Dim loadedDocument As PdfLoadedDocument = New
PdfLoadedDocument("../../Data/Barcode.pdf")
pdfViewer.Load(loadedDocument)
'Export the particular PDF page as image at the page index of 0
Dim image As Bitmap = pdfViewer.ExportAsImage(0)
'Save the image.
image.Save("Sample.jpg", ImageFormat.Jpeg)
Steps to convert a specific range of pages of the PDF file into JPG images programmatically:

PdfViewerControl pdfViewer = new PdfViewerControl();
//Load the input PDF file
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("../../Data/Barcode.pdf");
pdfViewer.Load(loadedDocument);
//Export all the pages as images at the specific page range
Bitmap[] image = pdfViewer.ExportAsImage(0, loadedDocument.Pages.Count - 1);
for (int i = 0; i < image.Length; i++)
{
// Save the image.
image[i].Save("Sample" + i.ToString()+".jpg", ImageFormat.Jpeg);
