addTextStamp error

Aspose.PDF Product Family

Hello,

I’m using Aspose.Pdf to add text stamps to pdf. The code seems to work fine but i can’t open in some cases the new pdf files with Acrobat Reader DC.

I recieve the following messages:
-> “An error exists on this page. Acrobat may not display the page correctly. Please cotnact the person who created the PDF document to correct the problem”
-> "Coannot find of create the font ‘RKNJFU+Tahoma’. Some characters may not display or print correctly. ".

The final document is diplayed with dots where the text stamp should have been. I can see the final document with other pdf readers, browsers etc, correctly, but i’d like to know if i can fix the problem i’m experiencing with acrobat reader.

I’m sending you the original doc and the doc after i added the text stamp:
123.pdf (216.2 KB)
123 (1).pdf (239.2 KB)

and the code sample:

public int AsposePdfAddTextStamp(string inputFile, string outputFile, string text1, string text2, int topMargin1, int topMargin2, string fontName, int fontSize, int horizontalAlignment, int leftMargin, int rightMargin, int wherePage, ref string errorMessage)
{
try
{
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(inputFile);

            if (text1.Length > 0)
            {
                TextStamp textStamp = Utils.createTextStamp(text1);
                textStamp.Background = false;
                textStamp.TopMargin = topMargin1;
                if (leftMargin > 0)
                    textStamp.LeftMargin = leftMargin;
                if (rightMargin > 0)
                    textStamp.RightMargin = rightMargin;
                if (horizontalAlignment == 0)
                    textStamp.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Right;
                else if (horizontalAlignment == 1)
                    textStamp.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;
                else if (horizontalAlignment == 2)
                    textStamp.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Left;
                textStamp.VerticalAlignment = Aspose.Pdf.VerticalAlignment.Top;

                textStamp.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont(fontName);
                textStamp.TextState.FontSize = fontSize;
                //textStamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Blue);
                if (wherePage == 0)
                    pdfDocument.Pages[1].AddStamp(textStamp); // 1 είναι η πρώτη σελίδα
                else if (wherePage == 1)
                    pdfDocument.Pages[pdfDocument.Pages.Count].AddStamp(textStamp); // τελευταία σελίδα
                else if (wherePage == 2)
                {
                    pdfDocument.Pages[1].AddStamp(textStamp); // πρώτη σελίδα
                    pdfDocument.Pages[pdfDocument.Pages.Count].AddStamp(textStamp); // τελευταία σελίδα
                }
            }

            if (text2.Length > 0)

Facades.FormattedText text = new Facades.FormattedText(str);
text.AddNewLineText(DateTime.Now.ToString());
TextStamp textStamp = new TextStamp(str);
textStamp.TextState.Font = FontRepository.FindFont("Arial");
string strSize = "50";
textStamp.TextState.FontSize = Convert.ToSingle(strSize);
textStamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Blue);
textStamp.Opacity = 0.5;
