code used:

//Uses the Syncfusion.EJ2.PdfViewer assembly

PdfRenderer pdfExportImage = new PdfRenderer();

//Loads the PDF document

pdfExportImage.Load(@"currentDirectory\..\..\..\..\Data\HTTP Succinctly.pdf");

//Exports the PDF document pages into images

Bitmap bitmapimage = pdfExportImage.ExportAsImage(0, 200, 200);

//Save the exported image in disk

bitmapimage.Save(@"currentDirectory\..\..\..\..\Images\" + "bitmapImage" + i.ToString() + ".png");
