How to preserve Tamil language in a PDF document?
Syncfusion Essential PDF is the .NET PDF library used to create, read, and edit PDF documents. Using this library, you can draw the complex script language text (Tamil) in a PDF document.
Steps to preserve Tamil language in PDF document programmatically:
- Create a new C# console application project.
- Install the Syncfusion.Pdf.WinForms NuGet package as reference to your .NET Framework applications from NuGet.org.
- Include the following namespaces in the Program.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics
- Enable the ComplexScript property in the PdfStringFormat instance to draw the complex script layout texts.
//Create a new instance for the PdfStringFormrat PdfStringFormat format = new PdfStringFormat(); //Set the format to complex script layout type format.ComplexScript = true;
- Use the following C# and VB.NET code snippets to draw the complex script text (Tamil) in PDF document.
C#
//Create a new PDF document
PdfDocument doc = new PdfDocument();
//Add a page to the document
PdfPage page = doc.Pages.Add();
//Initialize the PDF page graphics
PdfGraphics graphics = page.Graphics;
//Set the font with Unicode option
Font font = new Font("Nirmala UI", 14);
PdfFont pdfFont = new PdfTrueTypeFont(font, true);
//Create a new instance for the PdfStringFormrat.
PdfStringFormat format = new PdfStringFormat();
//Set the format as complex script layout type
format.ComplexScript = true;
//Draw the text to page graphics
graphics.DrawString("பேசுதல்", pdfFont, PdfBrushes.Black, new RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height), format);
//Save the document
doc.Save("output.pdf");
//Close the document
doc.Close(true);
VB.NET
'Create a new PDF document
Dim doc As New PdfDocument()
'Add a page to the document
Dim page As PdfPage = doc.Pages.Add()
'Initialize the PDF page graphics

format.ComplexScript = True
'Draw the text to page graphics
graphics.DrawString("பேசுதல்", pdfFont, PdfBrushes.Black, New RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height), format)
