Steps to draw the complex script text in a PDF document programmatically:

3. Include the following namespaces in the Program.cs file.

C#

using Syncfusion.Pdf;
using Syncfusion.Pdf.Graphics;
using Syncfusion.Drawing;

4. Use the following code sample in Program.cs to draw the complex script text in a PDF document.

C#

//Create a new PDF document.
PdfDocument document = new PdfDocument();
//Add a page.
PdfPage page = document.Pages.Add();
//Initialize the PDF page graphics.
PdfGraphics graphics = page.Graphics;
// Open a file stream.
FileStream fontStream = new FileStream(@"../../../NirmalaB.ttf", FileMode.Open, FileAccess.Read);
// Create a PdfTrueTypeFont object.
PdfFont font = new PdfTrueTypeFont(fontStream, 14);
FileStream arabicFontStream = new FileStream(@"../../../arial.ttf", FileMode.Open, FileAccess.Read);
// Create a PdfTrueTypeFont object.
PdfFont arabicFont = new PdfTrueTypeFont(arabicFontStream, 14);
// Create a PdfStringFormat object for text formatting.
PdfStringFormat format = new PdfStringFormat();
// Enable complex script support for the string format.
format.ComplexScript = true;

//Draw the Tamil text to page graphics. 
graphics.DrawString("பேசுதல்", font, PdfBrushes.Black, new RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height), format);

//Draw the Hindi text to page graphics. 
graphics.DrawString("मेरा नाम है दिनेश", font, PdfBrushes.Black, new RectangleF(0, 50, page.GetClientSize().Width, page.GetClientSize().Height), format);

//Draw the Arabic text to page graphics. 
graphics.DrawString("مرحبا", arabicFont, PdfBrushes.Black, new RectangleF(0, 100, page.GetClientSize().Width, page.GetClientSize().Height), format);

//Creating the stream object.
MemoryStream stream = new MemoryStream();
//Save the PDF document to stream.
document.Save(stream);
// Write the content of the memory stream to an output PDF file.
File.WriteAllBytes("Output.pdf", stream.ToArray());
//Close the document.
document.Close(true);
