Hi Sarath, 

Yes, the documentation link for drawing text and images to the PDF document works in dot net Core 2 also. It is not possible to save PDF document directly to specified file location in dot net core platform, instead we can save using memory stream. 

Please find the below code snippet for more details : 

            //Create a new PDF document. 
            PdfDocument doc = new PdfDocument(); 
            //Add a page to the document. 
            PdfPage page = doc.Pages.Add(); 
            //Create PDF graphics for the page 
            PdfGraphics graphics = page.Graphics; 
            string imagePath = _hostingEnvironment.WebRootPath + "image.jpg"; 
            Stream imageStream = new FileStream(imagePath, FileMode.Open); 
            //Load the image from the disk. 
            PdfBitmap image = new PdfBitmap(imageStream); 
            //Draw the image 
            graphics.DrawImage(image, 0, 0); 
            //Saving the PDF to the MemoryStream 
            MemoryStream stream = new MemoryStream(); 
            //If the position is not set to '0' then the PDF will be empty. 
            stream.Position = 0; 
            FileStreamResult fileStreamResult = new FileStreamResult(stream, "application/pdf"); 
            fileStreamResult.FileDownloadName = "Sample.pdf"; 

Please let us know if you need further assistance.
