[Steven Hongbin Zhou]

Hi I am trying to use SyncfusionGraphics.PdfTextElement to draw a Arabic text(سیتوژنتیک_) on pdf page, but all of the chars become to question marks,so how to draw a Arabic text on pdf page? below is my code:

Syncfusion.Pdf.Graphics.PdfStringFormat format = new Syncfusion.Pdf.Graphics.PdfStringFormat();
format.Alignment = Syncfusion.Pdf.Graphics.PdfTextAlignment.Left;
SyncfusionGraphics.PdfTextElement text = new SyncfusionGraphics.PdfTextElement()
        {
            "سیتوژنتیک"
            Font = font,
            StringFormat = format,
            Brush = this.GetPdfBrush(textBlockInfo.FontColor)
        };
       
    text.Draw(page, position,
                 page.Size.Width - page.Section.PageSettings.Margins.Left - page.Section.PageSettings.Margins.Right, layoutFormat);

Hi Steven,

Thank you for your interest in Syncfusion products.

I am afraid that I was not able to reproduce the problem when drawing Arabic text with embedded font. I had placed the code snippet in the below:

PdfDocument document = new PdfDocument();

PdfPage page = document.Pages.Add();

PdfStringFormat format = new PdfStringFormat();

format.Alignment = PdfTextAlignment.Left;

PdfTextElement text = new PdfTextElement();

text.Text = "سیتوژنتیک";

text.Font = new PdfTrueTypeFont(new Font("Arial", 10f), true);

text.StringFormat = format;

text.Brush = PdfBrushes.Black;

text.Draw(page, PointF.Empty);

document.Save("Sample.pdf");

document.Close(true);

Could you please try this and let me know if you still see the problem?

Regards

Geetha

Hi Geetha

I tried your source code, the Arabic text display. But when I use below test case, the chars "基因遗传学" was lost, do you know how to resolve this issue?

 PdfDocument document = new PdfDocument();
            PdfPage page = document.Pages.Add();

            PdfStringFormat format = new PdfStringFormat();
            format.Alignment = PdfTextAlignment.Left;

            PdfTextElement text = new PdfTextElement();
            text.Text = "559_XXXXXRegionsOfInterestسیتوژنتیک基因遗传学_.hg19.bed";
            text.Font = new PdfTrueTypeFont(new Font("Arial", 10f), true);
            text.StringFormat = format;
            text.Brush = PdfBrushes.Black;
            text.Draw(page, PointF.Empty);
            document.Save("Sample.pdf");
            document.Close(true);

The attachment file is my test restult.

Thanks
Steven

Hi Steven,

Thank you for the details.

It appears that Chinese characters cannot be displayed using "Arial" font in Adobe. To draw both Arabic and Chinese texts, please make use of "Arial Unicode MS" font or other equivalent font. Here is the code snippet.

text.Text = "559_XXXXXRegionsOfInterestسیتوژنتیک基因遗传学_.hg19.bed";

text.Font = new PdfTrueTypeFont(new Font("Arial Unicode MS", 10f), true);

Please try this and let me know if you have any questions.

Regards

We can draw the Arabic text with right-to-left (RTL) format in a PDF document in Xamarin Platform. We have to embed the font files in Xamarin Forms application by setting the build action to embedded resource. Please follow the below steps in your end and let us know if it is suites your requirement or not,

• Include the supported font file into the Assets folder.
• Right click the font file and Go to properties and Set Build Action to Embedded resource and copy always

Please find the below screenshot,

Note: Please make sure the using font file should supports the Arabic text or not. We have to use the supported font file to preserve the text properly.

Please refer the below link for more information,
