Hi Abdel, 

 

Thank you for contacting Syncfusion support.

 

We can draw the Arabic text with right-to-left (RTL) format in a PDF document by using DrawString method of PdfGraphics class in Xamarin Platform. Please refer the below code snippet to draw Arabic RTL text in Xamarin and let us know the result, 

string text = "بالعالم مرحبا !"; 

PdfTrueTypeFont font = new PdfTrueTypeFont(fontStream, 12); 

    

//Create a PdfStringFormat.  

PdfStringFormat format = new PdfStringFormat(); 

//Set text direction.   

format.TextDirection = PdfTextDirection.RightToLeft; 

             

//Set text alignment.   

format.Alignment = PdfTextAlignment.Right; 

 

SizeF pageSize = page.GetClientSize(); 

//Draw text to the PDF document.  

page.Graphics.DrawString(text, font, PdfBrushes.Black, new Syncfusion.Drawing.RectangleF(0, 0, pageSize.Width, pageSize.Height), format);
