Changes not visible in Adobe illustrator

  1. We are using PdfFileStamp Class to place multiple PDF’s in a one base PDF

  2. Also we are using TextFragmentAbsorber and TextFragmentCollection Classes for find and replacing text in PDF.

The above functions are working fine and changes reflected in output pdf file as expected but when we open the same file in adobe illustrator the changes are not reflected.

We have attached input and output files for your reference.


  1. The source pdf file was generated from adobe illustrator. Since we need a vector based file for printing.
  2. Aspose PDF version 23.5.0

Input 1.pdf (343.0 KB)
Input 2.pdf (302.0 KB)

Find and replace output.pdf (357.8 KB)
File stamping output.pdf (423.7 KB)


Would you please share the version of Adobe Illustrator along with screenshots of the files how it is not showing the modified content? We will log an investigation ticket and share the ID with you.

We are using Adobe illustrator 2023 (v27.5).

Please find the screen capture.

We apologize for the trouble as we forgot to request for sample code. We need to investigate the actual reason behind this behavior and it is expected to be related with Adobe Illustrator. Nevertheless, we are logging an investigation task to carry out the analysis. Can you please share sample code snippet that you are using to add stamp and perform replace functionality? It would help us in investigating the scenario accordingly.

Hi @asad.ali,
behalf of @kxsubramani

Here is the Sample code we used for

  1. Find and replace Text :
   private static void FindAndReplaceText()
       Document pdfDocument = new Document(@"input.pdf");
       TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("EMAIL");
       textFragmentAbsorber.TextReplaceOptions.ReplaceAdjustmentAction = 

       TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

       foreach (TextFragment textFragment in textFragmentCollection)
           textFragment.Text = "sample replaced text";

  1. Add stamp to PDF
    private static void GeneratedPrintLayout()
        string dataDir = @"C:Desktop\samples\";
        float originX = 0;
        float originY = 10;

        Document pdfDocument = new(dataDir + "Layout.pdf");
        PdfFileStamp fileStamp = new(pdfDocument);

        for (int i = 0; i < 4; i++)
            Aspose.Pdf.Facades.Stamp stamp = new();
            stamp.BindPdf(dataDir + "Input_1.pdf", 1);

            stamp.SetOrigin(originX, originY);

            if (i == 3)
                stamp.Rotation = 90.0F;

            originX += 250;
        fileStamp.Save(dataDir + @"output.pdf");
