شروع کار با iTextSharp

معمولا برای کار با iText یک سری روال تکراری از قبیل انتخاب نام فایل نهایی، تعریف فونت، سایز کاغذ، حاشیه بندی و ... را باید طی کنید که کدهای آن را در ذیل مشاهده می‌کنید:

            var fileStream = new FileStream("card.pdf", FileMode.Create, FileAccess.Write, FileShare.None);

            var docFont = GetFont();

            var pageSize = PageSize.A6.Rotate(); // سایز کارت را اینجا باید مشخص کرد

            var doc = new Document(pageSize);

            doc.SetMargins(18f, 18f, 15f, 2f);

            var pdfWriter = PdfWriter.GetInstance(doc, fileStream);

            doc.Open();

برای درج عکس به صورت شفاف در پس زمینه کارت باید از کد زیر استفاده کرد:

            //  درج لوگوی مسابقات به صورت شفاف در پس زمینه
            var canvas = pdfWriter.DirectContentUnder;
            var logoImg = Image.GetInstance(competitionImagePath);
            logoImg.SetAbsolutePosition(0, 0);
            logoImg.ScaleAbsolute(pageSize);
            var graphicsState = new PdfGState { FillOpacity = 0.2F };
            canvas.SetGState(graphicsState);
            canvas.AddImage(logoImg);

            // جدولی که برای چیدمان عناصر ارم دانشگاه و عنوان و عکس شخص استفاده می‌شود
            var topTable = new PdfPTable(3)
            {
                WidthPercentage = 100,
                RunDirection = PdfWriter.RUN_DIRECTION_RTL,
                ExtendLastRow = false,
            };

            var universityLogoImage = Image.GetInstance(universityLogoPath);

            universityLogoImage.ScaleAbsolute(70, 100);

            topTable.AddCell(new PdfPCell(universityLogoImage)
            {
                HorizontalAlignment = Element.ALIGN_LEFT,
                Border = 0
            });

            topTable.AddCell(new PdfPCell(new Phrase("کارت مسابقات دانشگاه آزاد اسلامی", docFont))
            {
                RunDirection = PdfWriter.RUN_DIRECTION_RTL,
                HorizontalAlignment = Element.ALIGN_CENTER,
                Border = 0,
            });

            var userImage = Image.GetInstance(userModel.ImagePath);
            userImage.Border = Rectangle.TOP_BORDER | Rectangle.RIGHT_BORDER | Rectangle.BOTTOM_BORDER | Rectangle.LEFT_BORDER;
            userImage.BorderWidth = 1f;
            userImage.BorderColor = new BaseColor(204, 204, 204); // gray color
