I am using a custom object and trying to write the data into a pdf to generate an invoice. However, im getting certain errors, and am not able to write a few things to the document. It would be very grateful if anyone could help me out of this. Here is my code:
public string InvoiceGenerator()
{
string random = (new Random().Next(1, 100)).ToString();
string virtualFilename = ConfigurationManager.AppSettings["InvoiceDirectoryFullPath"] + "/" + random + ".pdf";
string absolutefilePath = System.Web.Hosting.HostingEnvironment.MapPath(virtualFilename);
using (FileStream fs = new FileStream(absolutefilePath, FileMode.Create))
{
Document document = new Document(PageSize.A4, 25, 25, 30, 10);//left,right,top,bottom margins
try
{
using (PdfWriter writer = PdfWriter.GetInstance(document, fs))//;
{
document.Open();
if (company == null || client == null || project == null)
throw new Exception("Company/Client/Project Data is not present!!");
Paragraph p1 = new Paragraph();
string x = System.Web.Hosting.HostingEnvironment.MapPath(company.LogoUrl);
iTextSharp.text.Image companyLogo = iTextSharp.text.Image.GetInstance(x);
companyLogo.ScaleAbsolute(new Rectangle(100, 100));
companyLogo.SetAbsolutePosition(25, 740);
PdfContentByte cb = writer.DirectContent;
cb.AddImage(companyLogo);
//surround by a rectangle
cb.Rectangle(25, 740, 100, 100);
cb.Stroke();
//text begins here
//select font
BaseFont f_cb = BaseFont.CreateFont("c:\\windows\\fonts\\calibrib.ttf", BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
